Tips for Buying a Used A-Frame Trailer (Full Guide + Checklist)

Buying a used a-frame trailer is an excellent way to save money and avoid the initial decrease in value a new trailer sees immediately after towing it off the lot.

Did you know…
A new travel trailer typically loses 40% of its value in the first five years!

While buying a used a-frame trailer has its perks, there are a few things you need to be mindful of so you don’t end up spending more money in the long run on repair costs.

So, here’s what to look for when buying a used a-frame trailer, along with some important tips and a downloadable checklist to ensure you don’t miss anything.

Previous Maintenance

Maintenance history

The first step is to get a clear understanding of the trailer’s history. Just because it looks clean and well-kept doesn’t mean it was properly maintained or didn’t encounter other issues.

Ask the dealer or owner, depending on whether you are buying the camper from a lot or a private party, for any information or records about the vehicle’s past.

Unfortunately, you can’t just run a Carfax report on towable trailers to get the history.

A-Frame Exterior Checklist

Now, let’s inspect the trailer itself, starting with the exterior of the recreational vehicle.

Roof

One of the most neglected inspection checkpoints is the roof, but it’s one of the most important!

Why? A leaking roof can cause all sorts of issues, including water damage, mold, rotting of the structure, etc. And when this happens inside the walls, it can be hard to catch in a timely manner, requiring expensive repairs.

Roof Inspection Checklist:

  • Check the roof for cracks and damage, especially along seams.
  • Inspect the caulking and other seals for drying out or cracking.
  • Check around the AC unit (if applicable), vent covers, solar panels, roof racks, etc., for cracks in the seals or the units themselves.
  • Remove any vent covers and check for blockages, for example, debris build-up, animal nests, etc.
  • Lastly, spray it with a hose (ask the owner for permission first) and inspect the camper’s interior for dripping.

Exterior Walls

Walk around the A-frame’s exterior and inspect for any damage, including tears, holes, cracks, delamination, etc. 

Stand at one end of the trailer and peer down the side of it, looking for any malformation or bowing of the walls, which might signal a structural issue. Perform this step on the other side, ensuring the walls are level.

Windows and Doors

The windows and doors on an a-frame are another common entry point for moisture and are prone to other issues.

  • Check around the windows and doors for any dried, cracking, or shrinking seals. Spray down the a-frame trailer’s exterior with a hose and inspect the windows and doors for leaks.
  • Check the screens for any tears or rips.
  • Make sure the windows and doors open and close properly.
  • Inspect for any missing screws or components.
  • Ensure both the windows and doors properly latch/lock.

Awnings

If applicable, open the awnings and ensure they roll out smoothly. Inspect the awning material for any tears or rips. 

Lastly, make sure the awning closes smoothly and securely locks in place.

Pop-up

Pop up the camper and inspect the seals and any moving parts for damage or corrosion. If your a-frame features a slideout, test that, as well

If allowed, another spray test with your hose or pressure sprayer while the camper and, if applicable, the slideout is extended will help identify any water leaks.

Close the camper and ensure it operates smoothly.

LP System

A PDI (pre-delivery inspection) is performed by the dealership before they sell an RV, which includes a propane system inspection. With a private party seller, you might not be afforded that luxury.

So, if you’re working with an RV dealer, ask for a signed PDI form. If you’re working with a private seller and they haven’t performed an inspection, ask that they have it done. Who pays for the inspection will depend on how badly they want to sell it or how badly you want to buy it. You may even agree to split the cost.

Either way, we recommend a professional technician perform the propane system inspection.

Connections

Next, we want to check all the connections on the RV’s exterior, including the hitch, power connections, water tank hookups, and drains.

You may need to additionally inspect, if applicable:

  • Lighting connectors
  • Brake controllers
  • Tire pressure monitoring system

Ensure they are all in good working order.

Undercarriage

Finally, you’ll want to look under the trailer for any damage or wear and tear.

  • Check the axles, suspension, and other components for rust and corrosion.
  • Check the tires for proper pressure and the DOT code on the sidewall for the tire age to see if they need to be replaced. Unlike car tires, RV tires are often replaced due to age, as opposed to the amount of tread left (though it’s still a good idea to check the tread).

A-Frame Interior Checklist

Once you’ve completed the exterior checklist, it’s time to move inside the RV.

Electrical System

The electrical system often powers many essential components like your fridge, microwave, AC, lighting, entertainment devices, pumps, etc. 

So, it’s important to ensure the system runs properly, on both shore and battery power.

  • Start with the breaker box and make sure all of the switches are properly functioning and that none of them are tripped.
  • Test the RV’s electrical appliances and ensure they receive power and operate properly.
  • Test all of the lighting.
  • Test all of the electrical outlets to ensure they are receiving power.
  • Test any safety devices that may be hard-wired in.
  • If the RV has a battery (or batteries), ensure they are corrosion-free, have the proper voltage (around 12.6 volts), and check their age.

Water Damage and Mold

Water damage is one of the most common types of damage in an a-frame trailer. And as we explained above, it can wreak havoc on your camper, leading to costly repairs.

Signs of water damage can include:

  • Brown spots on the ceiling
  • Bowed or bubbling ceiling
  • Warped walls or floors
  • Mold

Windows and Doors

If you didn’t check the windows from the inside while running through the exterior checks above, now’s the time to ensure they open and close properly, the cranks or slides work, and they are sealed when shut.

Heating and Cooling System

Your trailer’s heating and cooling systems help make it livable, especially in extreme temperatures. So, we want to make sure these are in good working order.

Checking the AC

Turn on the air conditioning unit and ensure cold air blows out of all the vents. Let it run for 20 to 30 minutes and listen for any weird noises or squeaks. Ensure the inside temperature of the RV is indeed cooling down.

Additionally, you’ll want to ensure:

  • There are no leaks around the AC unit
  • The filters are clean
  • The fan mode works

Checking the RV Furnace

Turn on the furnace and ensure it fires up properly. Again, listen for any weird squeaking and ensure warm air comes from the vents.

Plumbing System

The last thing you want is plumbing issues the first time you take your new a-frame out on the road! They aren’t fun to clean up, can be hard to diagnose, and can lead to water damage.

There are a few major components we’ll want to inspect, including:

  1. Tanks: Hook the trailer to city water and fill the fresh water tank. Ensure the tanks fill properly and aren’t leaking. Unhook from city water.
  2. Fixtures: Test all the fixtures in the trailer, including the faucets, shower, toilets, etc.
  3. Water pump: Ensure the pump works properly and all fixtures receive water.
  4. Water heater: Ensure that the water heater powers on and that hot water flows out of the faucets.
  5. Drains: Once all the above has been tested, ensure the tanks drain properly.

Appliances

Test all kitchen appliances and ensure they are in good working condition. This will include testing the air temperature in the refrigerator and freezer, testing all of the burners on the stove and temperature in the oven, etc.

Remember, some appliances may use electricity and gas, so test them in both modes.

Entertainment Components

Check the operation of any TVs, satellite dishes, audio systems, wifi routers, etc., and any remotes that operate these components.

Safety Devices

Test all the safety devices and alarms in the a-frame trailer, including gas, carbon monoxide, and smoke detectors.

Be sure there is at least one up-to-date and functioning fire extinguisher.

Everything Else

Lastly, visually inspect every little nook and cranny of the trailer. Test storage cabinets, cupboards, and drawers, look for evidence of rodents, etc.
