If you’re wondering how to inspect a used RV, here’s the short answer:Check the roof first, look for water damage inside, inspect the undercarriage and frame, test every system, and verify paperwork before signing. A proper inspection can save you thousands in hidden repairs. We’ll walk you through exactly what to check on the roof, undercarriage, water systems, appliances, and more before buying a used RV in 2026.
Step 1: Inspect the Roof First
What to Check During an RV Roof Inspection
The roof is the most important area on any used RV.Look for:
- Soft spots when walking carefully
- Cracked or peeling sealant around vents and skylights
- Bubbling or rippling membrane
- Signs of patchwork repairs
- Separation at seams
Why It Matters
Water intrusion is the #1 cause of structural RV damage.Even a small crack in sealant can lead to long-term wood rot inside the walls.Pro Tip: Bring a ladder and inspect every inch, especially around AC units and front/rear caps.
Step 2: Look for Signs of Water Damage Inside
Water damage often hides in corners and cabinets.
Signs of RV Water Damage
- Staining on ceilings
- Soft or bubbling wall panels
- Musty smell
- Discoloration in cabinets
- Spongy flooring
Open every cabinet. Look inside storage compartments. Check around windows.If something smells off, trust your instincts.
Step 3: Inspect the Undercarriage and Frame
The undercarriage tells you how the RV was treated.
What to Check Underneath
- Rust on frame or axles
- Bent stabilizers or jacks
- Leaking holding tanks
- Loose wiring
- Sagging underbelly panels
In Indiana and surrounding Midwest states, road salt exposure can accelerate corrosion. Pay close attention if the RV was used year-round.
Step 4: Test All Water Systems
Turn Everything On
Do not skip this.
- Connect city water
- Fill the fresh tank
- Run all faucets
- Flush the toilet
- Check shower pressure
- Inspect under sinks for leaks
Look for:
- Dripping fittings
- Low water pressure
- Water pump running continuously
- Signs of previous repairs
Water system repairs can range from $200 to $2,500 depending on the issue.
Step 5: Check Appliances and Electrical Systems

Step 6: Inspect Tires and Suspension
Tires often age out before they wear out.Check:
- DOT date codes (over 5–6 years old may need replacing)
- Cracks in sidewalls
- Uneven tread wear
- Leaf springs and equalizers
A full tire replacement can cost $800–$2,500 depending on RV size.
Step 7: Review Paperwork and Ownership History
Before buying, verify:
- Clear title
- VIN matches paperwork
- Service records
- Recall completion
You can check recall history through the National Highway Traffic Safety Administration website.If buying from a private seller, request maintenance documentation.
Should You Hire a Professional Inspector?
If you’re spending $40,000–$80,000, a professional pre purchase RV inspection may cost $300–$800 and could save you thousands. However, buying from a dealership that pre-inspects inventory can reduce risk significantly.
