Buying a Used RV? Don’t Skip This Inspection Checklist

Buying a motorhome or travel trailer is a major investment, and a professional RV inspection can help you uncover expensive problems before you buy. Whether you're purchasing from a dealership or a private seller in Northern California, taking the time to inspect the RV's major systems, structure, appliances, and safety equipment can save you thousands of dollars in unexpected repairs.

1. Start With the RV's Exterior

Begin by walking completely around the RV and looking for signs of water intrusion, accident damage, poor repairs, or neglected maintenance.

• Inspect the roof for cracks, tears, bubbles, soft spots, and damaged sealant
• Check roof vents, skylights, antennas, and other roof penetrations
• Inspect exterior walls for bubbles, delamination, cracks, or discoloration
• Look for signs of previous water damage around windows and doors
• Inspect exterior storage compartments for moisture, rust, or corrosion
• Check doors, windows, locks, and latches for proper operation
• Inspect slide-out seals and surrounding wall areas
• Test awnings and inspect fabric, arms, motors, and mounting hardware
• Look underneath the RV for leaks, corrosion, damaged components, or evidence of repairs

Water intrusion is one of the biggest concerns when buying a used RV. Pay particular attention to soft flooring, stained ceilings or walls, musty odors, bubbling wall panels, and fresh sealant that may be covering an older problem.

2. Inspect the Interior

A clean interior doesn't necessarily mean the RV has been well maintained. Look beyond cosmetics and inspect the condition of the structure and living systems.

• Check ceilings, walls, and floors for stains or soft spots
• Look inside cabinets and storage areas for water damage
• Check for mold, mildew, or persistent musty odors
• Inspect flooring for buckling, soft areas, or separation
• Test doors, drawers, cabinet hardware, and furniture
• Inspect upholstery, mattresses, and window coverings
• Check for signs of rodent or pest damage
• Verify that smoke, carbon monoxide, and propane detectors are present and operational

3. Test the Electrical System

The RV's electrical system should be tested rather than simply switched on and off.

• Test all interior and exterior lights
• Test every 120-volt electrical outlet
• Test GFCI outlets
• Inspect the shore-power cord and connection
• Check the converter/charger
• Test the house batteries and battery connections
• Check the battery compartment for corrosion or damage
• Test the inverter, if equipped
• Check the generator, if equipped
• Look for improperly modified or damaged wiring
• Verify that electrical appliances operate properly

For a motorhome, the chassis electrical system should also be evaluated separately from the RV's house systems.

4. Check the Plumbing System

Plumbing problems can quickly become expensive, particularly when hidden leaks have caused structural damage.

• Fill and test the freshwater system
• Inspect faucets and sinks for leaks
• Test the shower and bathroom fixtures
• Check toilet operation and seals
• Inspect visible water lines and fittings
• Test the water pump
• Check the water heater
• Inspect the freshwater tank
• Inspect gray and black holding tanks
• Test tank-monitoring systems
• Look underneath sinks and cabinets for hidden leaks

If plumbing problems are discovered, have them professionally evaluated before completing the purchase. A minor leak can sometimes indicate a much larger underlying issue.

5. Test Propane and Appliances

RV appliances can be expensive to replace, so make sure they work before purchasing the vehicle.

• Inspect the propane tank or cylinders
• Check visible propane lines and connections
• Test the stove and oven
• Test the refrigerator on available operating modes
• Test the furnace
• Test the water heater
• Test the air conditioner
• Test the microwave
• Test the washer/dryer, dishwasher, or other installed appliances
• Verify that appliance ventilation systems are unobstructed

6. Inspect Slides, Awnings, Jacks, and Leveling Systems

Mechanical components that move should be operated multiple times during the inspection.

• Extend and retract every slide-out
• Listen for unusual noises during slide operation
• Check slide floors and seals
• Inspect slide motors, mechanisms, and wiring
• Extend and retract the awning
• Test electric or hydraulic leveling jacks
• Inspect jack pads and mounting areas
• Test stabilizers on travel trailers and fifth wheels
• Look for hydraulic fluid leaks

7. Motorhome Mechanical Inspection

If you're buying a motorhome, the chassis deserves the same attention as the living area.

• Inspect engine fluids and look for leaks
• Check belts and hoses
• Inspect the cooling system
• Check the transmission
• Inspect steering components
• Check suspension components
• Inspect brakes
• Check shocks and other suspension components
• Inspect tires for age, cracking, uneven wear, and damage
• Check the condition of the batteries
• Look underneath the chassis for leaks, corrosion, or damage
• Review available maintenance and service records
• Perform a road test when appropriate

A professional RV inspector may evaluate the coach systems while a qualified automotive technician evaluates the engine, transmission, chassis, and other automotive components.

8. Travel Trailer and Fifth-Wheel Inspection

Towable RVs have additional components that should be carefully examined before purchase.

• Inspect the frame for cracks, bends, corrosion, or repairs
• Inspect the hitch or fifth-wheel assembly
• Check safety chains and breakaway system
• Test the electric brakes
• Inspect axles and suspension components
• Check wheel bearings and hubs
• Inspect tires for age and condition
• Check wheels and lug nuts
• Inspect the trailer wiring and electrical connector
• Verify that exterior marker lights and brake lights work
• Inspect the landing gear and stabilizers
• Check for signs of frame or suspension damage

9. Check the Tires

Don't judge RV tires by tread depth alone. Tire age and condition are particularly important on RVs that may sit for extended periods.

• Check tire size and load rating
• Inspect tread condition
• Look for sidewall cracking
• Check for uneven wear
• Look for bulges or other damage
• Check tire pressure
• Check the tire date codes
• Inspect the spare tire, if equipped

10. Review the RV's History and Documents

Before purchasing, compare the physical condition of the RV with its paperwork and maintenance history.

• Verify the VIN
• Review the title and registration
• Check available maintenance records
• Ask for records of major repairs
• Determine whether the RV has been involved in an accident
• Ask about previous water damage
• Ask whether the RV has been stored indoors or outdoors
• Determine how frequently the RV was used
• Review warranty and service-contract information
• Compare the VIN and vehicle information with the seller's documentation

11. Take a Test Drive

For motorhomes, a road test can reveal problems that aren't apparent while parked.

• Steering response
• Brake performance
• Transmission shifting
• Engine performance
• Suspension noise
• Excessive vibration
• Alignment
• Warning lights
• Unusual engine or drivetrain noises
• Cruise control and dashboard functions

For towable RVs, the tow vehicle, hitch system, trailer brakes, and trailer handling should be evaluated appropriately.

12. Get an Independent RV Inspection

A professional inspection is especially valuable when buying a used RV because it provides an independent assessment before you commit to the purchase. A comprehensive inspection should evaluate the RV's major systems and document problems that may affect safety, reliability, or resale value.

When possible, choose an inspector who can evaluate the RV at its current location, whether that's a dealership, private residence, storage facility, or seller's property.

13. Don't Skip the Inspection Just Because It's New

A new RV isn't automatically problem-free. Manufacturing defects, improperly installed components, leaks, electrical problems, and appliance issues can still occur.

If you're purchasing a new RV from a dealer, perform a thorough pre-delivery inspection (PDI) before accepting the vehicle. Make sure identified problems are documented and addressed before you take possession.

14. Know When to Walk Away

Some problems should cause you to reconsider the purchase or renegotiate the price.

• Significant structural damage
• Extensive water intrusion
• Severe delamination
• Major roof deterioration
• Frame damage
• Serious tire or brake problems
• Evidence of a major accident
• Extensive electrical modifications
• Significant mold or moisture damage
• Major engine or transmission problems
• Multiple unresolved mechanical or appliance failures
