Buying a used RV can save you thousands, but only if you know what to look for. Too many RV shoppers fall in love with a unit’s floor plan or price tag, only to discover hidden problems later. Roof leaks, water damage, frame rust, or worn-out electrical systems can turn your dream rig into a money pit.

That’s why we created The Ultimate Used RV Inspection Checklist, a step-by-step guide to help you inspect every inch of your RV before you buy. From roof seals to tire tread, this list ensures nothing slips through the cracks.

Why an RV Inspection Matters Before You Buy

A used RV can offer tremendous value, but only if it has been properly maintained. Every component, from the roof to the frame, plays a role in keeping you safe and comfortable on the road. A used rig might look spotless on the surface while hiding serious (and expensive) issues underneath. Over time, wear and exposure to the elements can cause damage that may not be visible at first glance. Without a detailed inspection, those small issues can grow into costly repairs once you hit the highway.

A careful review helps identify signs of water intrusion, electrical faults, and mechanical wear before they become major problems. It also provides insight into how the RV was cared for by the previous owner. Maintenance records, tire condition, and appliance functionality all tell part of a story. 

Beyond preventing unexpected repairs, an inspection supports smarter negotiations and can help you: 

• Save money on costly post-purchase repairs
  
  
• Stay safe by catching mechanical or electrical faults
  
  
• Protect your resale value by maintaining a solid foundation
  
  
• Buy with confidence, knowing exactly what you’re getting

By performing a complete evaluation, or purchasing from a dealer who does, you gain confidence that your next journey will begin on solid ground. All Campers Inn RV used units are fully inspected before sale. Learn more about our certified process.

The Complete Used RV Inspection Checklist

Exterior Inspection

The exterior of an RV reveals a great deal about its overall condition. Start by walking around the entire unit, taking note of any cracks, dents, or discoloration on the body panels. Look closely at the roof, seams, and corners for dried or cracked sealant, which can allow moisture to seep inside. Even a small leak can lead to structural damage or mold if ignored.

Inspect the windows, doors, and slide-outs for tight seals and smooth operation. Gaps or uneven alignment may indicate underlying frame or water issues. Examine the awning for tears, mildew, and secure mounting hardware. If possible, extend and retract it to ensure it operates properly.

Tires deserve special attention. Check for uneven wear, dry rot, or sidewall cracks. Tires that appear new but have old date codes can still be unsafe. Don’t overlook the undercarriage - look for rust, corrosion, or damage to stabilizers and holding tanks.

Lighting is another key element. Confirm that headlights, brake lights, and turn signals work correctly. A complete exterior review sets the foundation for a successful inspection and helps you spot signs of neglect before making a commitment.

Pro Tip: Bring a flashlight and a moisture meter if you’re inspecting a unit privately.

Interior Inspection

Once the exterior passes a visual check, move inside and take time to examine the details. The interior can reveal how an RV was treated throughout its lifetime. Start by inspecting the floor for soft spots or uneven areas, which may signal hidden water damage. Look closely to ceilings and walls for discoloration, bubbling, or a musty odor. These are all signs that moisture has made its way in.

Open every cabinet, drawer, and storage compartment. Check that doors close smoothly and that there are no signs of mold or pests. Turn on interior lights and test outlets using a small plug-in tester. If anything flickers or fails to power on, it could point to an electrical problem.

Next, check the appliances. Turn on the refrigerator, stove, air conditioner, and furnace to confirm they all function correctly. Test faucets, showerheads, and toilets for water pressure and leaks. A full interior inspection provides a clear sense of whether the RV was properly cared for and maintained.

Mechanical and Electrical Systems

The heart of any RV lies in its systems. Whether performing a basic check or a full motorhome inspection, take time to verify each component’s performance. Start with the electrical system. Inspect the batteries for corrosion and ensure all terminals are clean and tight. Test the converter and inverter by plugging in to shore power to verify the system charges correctly.

If the RV has a generator, run it for several minutes and listen for steady operation. Check that it powers interior outlets and appliances as expected. Examine the propane system next. Make sure lines are free of leaks and the regulator operates properly. Turn on appliances that use propane, such as the water heater or stove, and confirm they light smoothly.

For the plumbing system, fill the fresh water tank and activate the pump. Look for leaks under sinks, near fittings, and around the water heater. Flush each faucet and toilet, then check for leaks once more after shutting off the water. Any signs of dripping or pressure loss may require repair before purchase.

Test Drive and Operational Checks

If the RV is drivable, the test drive is essential. Begin by checking fluid levels and ensuring the engine starts easily. During the drive, listen for unusual noises, feel for vibrations, and observe the responsiveness of the brakes and steering. You’re looking for a smooth and quiet ride, a good indication of solid mechanical health.

Monitor the oil and temperature gauge while driving. Rising temperatures or fluctuating pressure could suggest mechanical concerns. When parked, inspect the engine for leaks or frayed belts. Also, confirm that all lights, mirrors, and wipers work correctly.

For towable RVs, inspect the hitch, coupler, and safety chains for proper fit. Ensure the trailer brakes engage smoothly when tested. Leveling systems, stabilizers, and slide-outs should move evenly and quietly. Operational checks like these help reveal whether the RV performs as expected when it matters most, on the open road.

Before wrapping up the used RV inspection, conduct a secondary walk through with your checklist in hand. Note any repairs or concerns that need attention and verify that all systems function together. This final step ties it all together, giving you a clear understanding of the RV’s true condition.

A detailed inspection not only prevents unexpected repair bills but also ensures peace of mind. When each section - exterior, interior, mechanical, and operational - receives proper attention, buyers can make informed decisions and look forward to exploring the next destination with trust in their new-to-them RV.

DIY vs. Professional RV Inspection: Which Is Right for You?

Inspecting a used RV on your own can be rewarding, especially for experienced owners who understand how these systems work. A detailed checklist and a few basic tools can help uncover most visible issues. Buyers familiar with maintenance tasks like seal inspection, fluid checks, or appliance testing may feel comfortable handling the evaluation themselves. Performing the review personally also allows a closer connection to the vehicle, revealing subtle details that might go unnoticed during a quick walkthrough.

However, not every problem can be spotted with the naked eye. Some concerns, such as internal water damage, frame corrosion, or electrical irregularities, require specialized equipment and training to detect. In these cases, hiring a certified professional provides a deeper level of protection. An expert can run diagnostic tests, measure moisture content inside walls, and verify that all major systems meet safety standards.

If you’ve owned RVs before or are shopping for a smaller trailer, a DIY inspection may be enough. You’ll know what normal wear looks like and can identify common trouble areas.

However, if you’re buying a motorhome, luxury fifth wheel, or your first RV, it’s smart to bring in a professional. NRVIA-certified inspectors use moisture meters, borescopes, and diagnostic tools to uncover hidden problems before they cost you.

Or skip the stress. Every Campers Inn RV used unit is fully inspected and backed by our Integrity Pricing Promise.

Common Red Flags When Buying a Used RV

Even with the most thorough used RV inspection, certain warning signs should immediately raise concern. Recognizing these issues early can save both time and money while preventing future disappointment.

Evidence of Water Damage

Water intrusion is one of the most costly and common issues found in pre-owned RVs. Look for stains, soft spots, or bubbling in walls and ceilings. Press gently on corners and around windows to detect hidden moisture. A musty smell often signals ongoing leaks.

Fresh Caulk or Paint

Recently applied sealant or paint may indicate an attempt to cover up existing problems. Check whether the repair work looks consistent across the RV. Mismatched areas or sloppy finishes often reveal that something was concealed rather than corrected.

Tire and Suspension Problems

Tires more than five years old, even if they appear new, can fail unexpectedly. Uneven wear may suggest alignment or suspension damage. Examine axles, springs, and stabilizers for rust or cracks before purchase.

Electrical or Plumbing Concerns

Loose wiring, flickering lights, or inconsistent water pressure are warning signs of deeper system issues. Inspect around outlets and under sinks for corrosion or water stains. A functioning system should run quietly and evenly.

Missing Maintenance Records

An RV’s service history tells the story of its care. If the seller cannot provide maintenance receipts or inspection documentation, proceed cautiously. Regular oil changes, seal checks, and system testing indicate responsible ownership.

When one or more of these red flags appear, pause before committing. Each issue has the potential to become a significant expense once ownership changes hands. A careful review, or professional inspection when in doubt, ensures peace of mind before starting any adventure.

Watch out for:

• Persistent roof leaks or visible mold
  
  
• Fresh paint or caulk covering problem areas
  
  
• Damaged or spliced wiring
  
  
• Uneven tire wear (can signal suspension issues)
  
  
• Missing or incomplete maintenance records
