The RV Spring Shakedown Trip Checklist: What to Test After Dewinterizing

You flushed the antifreeze. The faucets run clear. The slides extend, the lights come on, the fridge gets cold on shore power. So you start packing for the first real trip of the season.

Stop. There is a step between dewinterizing and that first big trip, and skipping it is how most owners end up with a flooded bathroom floor, a dead fridge, or a soaked ceiling 300 miles from home.

That step is the shakedown trip. A short, deliberately close, deliberately boring first outing whose only job is to fail your RV in a recoverable way. You drive it. You sleep in it. You use every system the way you would on a real trip. And you find the things that survived storage on paper but did not survive storage in practice.

This guide walks through what a spring shakedown trip is, why driveway tests are not enough, where to go, and exactly which systems to actively test, not just glance at. By the end, you will know what to do this weekend so the first big trip later this summer is the one you were hoping for.

Dewinterizing is not a green light

Dewinterizing is a mechanical reset. You drain the antifreeze, sanitize the water system, reconnect batteries, open propane valves, and verify that systems power up. Done correctly, it gets your RV from "stored" to "functional."

What it does not do is simulate camping.

In your driveway, the rig is not moving. The tanks are not full. The fridge does not need to cool through a 90-degree afternoon. The roof has not been hit by an overnight rainstorm. The shore power connection has not been carrying the load of an AC, a microwave, a converter, and a water heater simultaneously for three hours. The slide seals have not had to keep water out during a thunderstorm.

All of those conditions reveal problems that a driveway test cannot. That is what a shakedown trip is for.

It is also worth saying clearly: a shakedown trip is not the same thing as the shakedown period new RV owners go through in their first 90 days. That is a months-long process of revealing factory defects on a brand-new rig. Our guide for new RV owners covers that in detail. The spring shakedown trip is the annual version every RV owner should take, regardless of how old the rig is, after winter storage.

Why driveway tests lie

Three forces work on an RV during actual use that simply do not exist in your driveway. Understanding these is what separates owners who treat shakedown trips seriously from owners who keep getting surprised.

Vibration. Water lines that hold pressure when static can fail when 12,000 pounds of trailer rolls down the highway at 65 mph. Fittings that the factory left half-tightened can finally let go. Wiring that survived storage can develop intermittent contact issues from road movement.

Sustained load. Your shore power cord might handle the toaster oven for one minute in the driveway. It might not handle the AC, the converter charging dead batteries, the water heater on electric, and the fridge for three hours straight on a hot afternoon. Weak connections reveal themselves under sustained load.

Time. A 30-second faucet test does not catch a fitting that drips once every two minutes. A 10-minute fridge test does not catch a unit that cools fine for the first hour then stalls. A daylight roof inspection does not catch a seal that only leaks during a sustained rain. Time exposes what brief tests cannot.

The shakedown trip exists specifically because all three of these forces are present during real camping and absent during dewinterizing.

Where to take a shakedown trip

The whole point is to find problems when finding them is easy. That changes the calculus on where to go.

Stay close. Less than an hour from home is ideal. Less than 30 minutes is even better. If something major fails, you want to be able to drive home, work on it in your own driveway with your own tools, and try again next weekend.

Pick a campground with full hookups. Shore power, fresh water connection, sewer connection. This is the only way to test the systems that connect to external utilities, which is most of the systems that matter.

Stay at least two nights, ideally three. One night is not enough time to surface slow leaks, intermittent issues, or systems that fail only after sustained use. Two nights covers most issues. Three nights gives you a full daily cycle to test heating overnight, cooling during the day, and water usage across a normal pattern.

Skip the destination camping. This is not the trip where you visit a national park or hit a bucket list location. Pick somewhere unremarkable nearby. You are testing the RV, not the campground.

The systems to actually test

Here is where most shakedown trip checklists get vague. They tell you to "check the water system" or "test propane appliances." That is not enough. You need to know what to do, for how long, under what conditions, and what to watch for.

For each system below, we cover what most owners do (often not enough), what they miss, and how to actually test it during the shakedown.

Water system under pressure and over time

Most owners turn on each faucet for a few seconds, watch water come out, and move on.

What that misses: slow leaks at fittings, slowly weeping connections behind walls, a water pump cycling on its own when nothing is running.

What to actually do:

Connect to city water and let the system sit under pressure for the full first day. Walk through the rig and check under every sink, behind the toilet, around the water heater, and at the water pump. Look for any moisture, any drip, any darkening of wood.

Run every fixture in sequence. Kitchen, bathroom sink, shower, toilet, outdoor shower if you have one, ice maker line if equipped. Hold each fixture open for at least 30 seconds. Watch the pressure stay steady.

Run two fixtures simultaneously. Kitchen and bathroom together. Shower and kitchen together. This stresses the system in a way a single fixture cannot.

Listen for the pump cycling on its own. Turn off city water and run from the tank for an afternoon. If the pump kicks on when nothing is running, you have a leak somewhere. Find it before you leave.

Fill the gray tank to half capacity and let it sit overnight. Check under the rig in the morning for any drips from gray tank fittings or valve seals.

Propane in real conditions

Most owners light the stove for a moment to confirm propane is flowing, then call propane "tested."

What that misses: a furnace that won't ignite on a cold morning, a fridge that won't run on propane after the first hour, a water heater that fails to switch from electric to gas.

What to actually do:

Light each propane appliance separately, on propane only, with the electric option turned off where applicable. Stove burners, oven, fridge on LP, water heater on LP, furnace.

Run the furnace overnight on the coldest night of the trip. If the weather is too warm to need heat, run it anyway for 20 minutes in the morning. You are testing ignition and cycling, not heating.

Run the fridge on propane for a minimum of 8 hours. This is the test that catches a fridge with a marginal propane igniter or a partial blockage in the gas circuit. A fridge that runs fine on shore power but stalls on propane is one of the most common failures after storage.

Run the water heater on propane for a full shower cycle. Cold to hot to cold to hot, multiple times. Confirm it relights on demand.

Smell test the propane locker and all appliance connections at the start of the trip. If you have soapy water with you, brush it on key fittings and watch for bubbles. A small leak you would not notice in a driveway can be more obvious when the system has been actively used.

The fridge across power sources

Most owners check that the fridge gets cold. They do not check that it gets cold on every power source the fridge claims to support.

What to actually do:

Pre-cool the fridge for 24 hours on shore power before the trip. This is the baseline.

During the trip, run on shore power for the first day. Confirm temperatures stay in the safe zone for both fresh and freezer compartments. A cheap fridge thermometer or two solves this.

Switch to propane for at least 8 hours on day two. Confirm the unit runs, the burner ignites, and temperatures hold.

If you have 12-volt cooling (some newer compressor-driven fridges), run on battery for several hours. Watch for the unit pulling battery voltage down faster than expected.

The fridge is the single appliance most likely to fail after storage and the most expensive one to replace. This is worth the time.

The roof during and after rain

Most owners inspect the roof on a dry day in the driveway. They look at the sealant, see no obvious cracks, and call it good.

What that misses: seals that look fine when dry but leak under sustained rain. Roof penetrations that have shifted over winter. Pinholes too small to see but big enough to admit water.

What to actually do:

Watch the weather forecast and try to schedule the shakedown trip around at least one night of rain. If the trip ends up dry, plan a follow-up rain test in your driveway later.

The morning after rain, walk the interior perimeter of every ceiling. Check every overhead cabinet, every roof-mounted appliance from below, every interior wall along the roof edge. Bring a flashlight. You are looking for any darkening, any moisture, any musty smell that was not there before.

Climb the roof in the morning after rain (carefully, with rubber-soled shoes) and look for pooling water in unexpected places. Water that pools is water that will eventually find its way through.

If you have not done a real roof inspection yet this season, our seasonal roof inspection guide walks through what to look for at each penetration and seam. That inspection plus this rain test is the strongest one-two punch you can throw against water damage.

Electrical under sustained load

Most owners plug in, see the lights work, and assume electrical is fine.

What that misses: weak shore power connections that get hot under sustained load, tired converters that can't keep up with combined demand, batteries that hold a surface charge but die quickly under real use.

What to actually do:

On day one, run several major loads simultaneously for at least an hour. AC on, microwave running for two minutes, converter charging batteries, water heater on electric. Touch the shore power cord at the pedestal, at the RV connection, and at the breaker panel. Anything noticeably warm needs attention.

Test outlets throughout the rig with a basic outlet tester ($5 at any hardware store). Confirm correct wiring and ground.

On a day with full sun, run on solar if you have it. Confirm the controller is reading correctly and batteries are charging.

Pull the shore power cord on day two and live off battery for a few hours during the day. Run the lights, the water pump, the propane fridge controls. Watch the battery voltage. A battery that drops faster than expected is on its way out, and you want to know that now.

Slides under real operation

Most owners cycle the slides once when they arrive at the campground.

What that misses: slides that develop binding after multiple cycles, motors that strain under repeated use, seals that leak under sustained pressure when extended.

What to actually do:

Extend and retract the slides at least twice during the trip. Watch the motors. Listen for new sounds. Watch the rate of movement; a slide that slows down partway through its travel is binding somewhere.

Check the slide seals visually with the slide extended. Look for compressed spots that should be uniform, gaps where the seal has shifted, or any visible damage.

If a rain night happens during the trip, check the interior floor along the slide edges the next morning. Slide seal leaks reveal themselves on the floor before they reveal themselves on the ceiling.

Tires after a real drive

Most owners check tire pressure before leaving and never look at the tires again.

What that misses: tires that look fine cold but show abnormal heat patterns after highway driving, pressure that drops faster than the other tires, sidewall cracks that were invisible in the driveway but become obvious after flexing.

What to actually do:

Set tire pressure cold the morning of departure. Use the pressure the manufacturer specifies on the placard inside the RV, not the maximum pressure on the sidewall.

Immediately upon arrival at the campground, walk around the rig and feel each tire. Significant differences in temperature across tires indicate a problem. A tire that is noticeably hotter than the others is dragging, low on pressure, or has internal damage.

Check pressure again the next morning when the tires are cold. Any tire that lost meaningful pressure overnight is a tire to watch for the rest of the trip.

Look at every sidewall in good light. Tires age out before they wear out, and small cracks that appear dormant in the driveway can spread under highway flex.

Brakes, bearings, and suspension (towable rigs)

Most owners do not test brakes deliberately. They just drive.

What that misses: brakes that drag after winter, wheel bearings that have lost grease and are running hot, suspension components that loosened during storage.

What to actually do:

Take a short highway run as part of the trip. Twenty minutes at highway speed is enough to surface problems.

When you arrive, immediately put your hand near (not on) each wheel hub. They should be warm. They should not be hot enough to hurt. A hub that is significantly hotter than the others is dragging or has a bearing problem.

Test the brake controller before any real driving. Most controllers have a manual slide that activates the trailer brakes only. Pull it on a quiet street and confirm the trailer brakes engage.

If you are towing and you have not had wheel bearings repacked in the last 12 months or 12,000 miles, schedule that service for after the shakedown. A failed bearing can cost you a wheel coming off the rig. This is one of the items the full RV maintenance checklist treats as non-negotiable.

Safety alarms (the test most owners skip entirely)

Most owners glance at the LP detector, see a green light, and call it tested.

What that misses: detectors that have expired, alarms with dead batteries, units that test successfully but no longer detect what they are supposed to detect.

What to actually do:

Press the test button on every detector. Smoke, carbon monoxide, propane. Each should sound when tested.

Check the expiration date printed on each detector. Most have a 5 to 10 year service life from manufacture date, not from purchase. Many RVs from the early 2010s are still running their original detectors, which are now expired regardless of whether they still chirp.

Replace batteries on any battery-powered detectors as a baseline. They cost a few dollars and might save your life.

Verify the fire extinguisher pressure gauge is in the green zone. Check the expiration date on the extinguisher itself.

This is one of the categories the RVKeeper Essentials Plan tracks automatically. The detectors and extinguishers are easy to forget exactly because they ask for nothing until they fail, which is the worst possible moment.

Keep a diary, not a memory

Here is the thing about shakedown trips: by the time you get home, you will have forgotten half of what you noticed.

You will remember the big things. The leak under the bathroom sink that you spent an hour mopping up. The fridge that took two hours to figure out. You will not remember the small things. The slide that seemed slightly slower than last year. The third outlet in the bedroom that did not work. The barely visible crack in the sealant near the roof vent. Those are the items that turn into the next expensive surprise.

Write everything down as it happens. A paper notebook in the RV works. The notes app on your phone works. So does anything else that is in your hand the moment you notice something.

Document by system. Roof. Water. Electrical. Propane. Slides. Tires. Brakes. Safety. For each item: what you noticed, when, what you were doing at the time, and whether you addressed it on the trip or it needs follow-up at home.

This is part of why RVKeeper exists. The app tracks every component on your specific rig, lets you log what was tested and when, and reminds you what is coming due. The shakedown trip is one of the highest-value entries you will make in any given year. It is also one of the easiest to lose track of if you are relying on memory alone.

After the shakedown: the punch list

When you get home, do not unhitch and walk away. The shakedown is not over until you have done the post-trip walkthrough.

Empty everything. Tanks, water lines, fridge, pantry. You are going back into normal storage between trips, and you want the rig clean.

Make the punch list. Three columns: safety items, expensive-if-ignored items, and comfort items. Safety items get fixed before the next trip, no exceptions. Expensive-if-ignored items get a deadline. Comfort items get a someday list.

Order parts now. Whatever you need for the punch list, order it this week. The lead time on RV parts is regularly two to six weeks. You do not want to discover at the start of June that the part you need does not arrive until July.

Schedule the dealer or mobile tech now. If anything on the punch list requires professional work, the spring backlog at most service departments is already running into July. Get on the calendar immediately.

Update your maintenance log. Everything you tested gets recorded. Everything that passed becomes a known good for this season. Everything that failed becomes a tracked item until it is fixed.

Frequently asked questions

What is an RV shakedown trip?

A shakedown trip is a short, deliberately close, deliberately boring first trip designed to test every system on your RV under real camping conditions before you commit to a longer trip. The goal is to surface problems while you are close to home and your tools, not 300 miles away.

How is a shakedown trip different from dewinterizing?

Dewinterizing is the mechanical process of flushing antifreeze, sanitizing water lines, and reconnecting batteries in your driveway. A shakedown trip is the act of actually using those systems under road vibration, sustained loads, and real-world conditions for at least two nights. Dewinterizing confirms systems power up. A shakedown confirms they perform.

How long should a spring shakedown trip be?

At least two nights, ideally three. One night is not long enough to surface slow leaks, intermittent issues, or systems that fail only under sustained use. Three nights gives you a full cycle of overnight heating, daytime cooling, and normal water and electrical usage.

Where should I take my shakedown trip?

Stay within an hour of home, ideally closer. Pick a campground with full hookups (electric, water, and sewer) so you can test every utility connection. Pick somewhere unremarkable. You are testing the rig, not the destination.

What system is most likely to fail on a first trip of the season?

The refrigerator on propane is one of the most common failures, followed by water system leaks at fittings that loosened during storage. Sealant cracks on the roof are also commonly revealed in the first spring rain. The fix for all three is the same: deliberate testing under real conditions before the big trip.

Do I still need a shakedown trip if my RV is new?

Yes, and probably even more so. New RVs reveal problems through real use that no inspection can catch. The first 30 to 90 days of ownership is its own shakedown process. Our guide for new RV owners covers what to expect during that period.

What if I find a major problem during the shakedown?

That is exactly what the shakedown is for. Drive home, address what you can yourself, and schedule professional work for anything beyond your skill level. The point of the shakedown is to find these things now, when you have time and proximity to fix them, rather than during a real trip when you do not.

---

The shakedown trip is the smallest investment you can make in protecting a real camping season. One weekend close to home. A notebook. A willingness to actually use every system, not just confirm it exists.

The first big trip of the year should be the trip you remember. Take the shakedown trip first, and it will be.
