10 common issues you should diligently look for when buying a new RV - 2025

When buying a new RV, it's crucial to understand that even straight from the factory, quality control issues can be common in the RV industry. Many dealerships and experienced RVers advise a thorough inspection, often by a certified professional, before taking delivery.

Here are 10 common issues you should diligently look for when buying a new RV:

1. Water Leaks and Seal Integrity:

   • What to check: This is the most critical issue. Inspect all roof seams, around vents, skylights, air conditioners, windows, doors, and slide-outs for any signs of poor caulking, gaps, cracks, or visible water stains (even faint ones). Check inside cabinets, under sinks, and near shower surrounds for any dampness or soft spots.
   • Why it's important: Water damage is often the most expensive and damaging problem in an RV, leading to rot, mold, and structural issues.

2. Slide-Out Operation and Seals:

   • What to check: Fully extend and retract all slide-outs several times. Listen for grinding, binding, or unusual noises. Ensure they extend and retract smoothly and evenly. Crucially, inspect the seals (wipers) around the slide-outs both when extended and retracted to ensure they are properly seated and free of tears or kinks.
   • Why it's important: Misaligned or faulty slide-outs can lead to water leaks, structural damage, and expensive repairs.

3. Electrical System Malfunctions:

   • What to check: Test every outlet (using a small appliance or phone charger), every light fixture (interior and exterior), and all switches. Ensure the converter and inverter are functioning correctly. Test the shore power connection and, if applicable, the generator.
   • Why it's important: Faulty wiring, tripped breakers, or non-functioning outlets can be a major inconvenience and potentially a safety hazard.

4. Plumbing System Leaks and Functionality:

   • What to check: Turn on all faucets (hot and cold), flush the toilet, and run the shower. Look and feel for leaks under all sinks, around the toilet base, and shower pan. Check the water pump operation (it should cycle on and off smoothly and stop once water flow ceases). Inspect all fresh, grey, and black tank valves for proper operation and leaks.
   • Why it's important: Plumbing issues, especially leaks, can cause significant water damage and unsanitary conditions.

5. Appliance Functionality (Refrigerator, AC, Furnace, Water Heater, Microwave, Stove/Oven):

   • What to check: Test every appliance in all its operating modes (e.g., refrigerator on electric and propane, furnace and AC on thermostat). Ensure the water heater heats water on both electric and propane (if applicable).
   • Why it's important: These are essential for comfort and can be expensive to repair or replace.

6. Structural Integrity (Flooring, Walls, Ceilings, Cabinets):

   • What to check: Walk the entire floor, pressing down to feel for any soft spots or unevenness, especially around doorways, the bathroom, and under sinks. Visually inspect walls and ceilings for bubbling, delamination (peeling layers), or bowing. Open and close all cabinets, drawers, and doors to ensure they latch properly and are securely mounted. Check for exposed wiring, loose screws, or excess sawdust in utility areas.
   • Why it's important: These indicate poor construction or hidden water damage.

7. Exterior Fit and Finish:

   • What to check: Look for dents, scratches, uneven paneling, or crooked graphics. Examine the condition of the roof membrane (no tears, bubbles, or loose spots). Check the tires for proper inflation, any signs of dry rot (even on a new RV if it's been sitting), and the date code (tires older than 4-5 years, even if "new," should be a concern). Inspect the ladder, awnings, and exterior storage compartment latches.
   • Why it's important: Cosmetic issues can indicate underlying manufacturing sloppiness, and tire condition is crucial for safety.

8. Propane System and Safety Features:

   • What to check: Ensure propane tanks are full (or at least partially filled for testing) and securely mounted. Check all connections for leaks (a soapy water test is ideal). Verify that the carbon monoxide detector, smoke detector, and fire extinguisher are present, operational, and not expired.
   • Why it's important: Propane leaks and non-functioning safety devices are severe hazards.

9. Chassis and Undercarriage (for Motorhomes/Towing for Trailers):

   • What to check (Motorhomes): Check engine oil, coolant, transmission fluid levels, and belts/hoses for proper condition. Look for any fluid leaks under the vehicle.
   • What to check (Towables): Ensure your tow vehicle's capacity matches the RV's GVWR (Gross Vehicle Weight Rating). Inspect the hitch connection, axles, suspension, and check for any rust or damage underneath.
   • Why it's important: The foundation of the RV is critical for safe operation.

10. Documentation and Manuals:

    • What to check: Ensure you receive all owner's manuals for the RV itself and all individual appliances and systems (water heater, furnace, refrigerator, etc.).
    • Why it's important: These manuals are invaluable for understanding how to operate and troubleshoot your RV.

Recommendation: Given the complexity of RVs and the prevalence of initial defects, it is highly recommended to hire an independent, certified RV inspector (e.g., NRVIA certified) to perform a comprehensive pre-delivery inspection (PDI) before you finalize the purchase of any new RV. They will find issues that the dealership's PDI might miss and can provide leverage for you to get items fixed before you drive off the lot.
