🛋 STRUCTURAL & EXTERIOR
How can I prevent or repair roof leaks?
Inspect your roof at least twice a year. Look for soft spots, cracks, or peeling sealant. Use self-leveling RV roof sealant to patch cracks and reseal seams. Keeping the roof clean and checking around vents, AC units, and skylights can prevent most leaks.
How do I inspect and reseal slideouts?
Extend your slideouts fully and inspect the seals along the top, sides, and bottom. Look for cracks, wear, or areas where water could seep in. Clean seals with mild soap and water, then apply rubber seal conditioner to keep them flexible. Reseal any gaps using appropriate slideout sealants. Also check the slide mechanism for smooth movement and strange noises.
What type of sealant should I use on the roof?
Use self-leveling lap sealant for horizontal surfaces (such as Dicor or Alpha Systems products). For vertical surfaces, use non-sag sealant. Always match the sealant to your specific roof type—EPDM, TPO, fiberglass, or aluminum. Do not use silicone unless specified by the manufacturer, as it may not adhere properly or remain flexible over time.
How do I maintain awnings and prevent damage?
Open and inspect your awnings regularly for tears, mildew, or sagging. Clean the fabric with a soft brush, water, and mild soap. Always let the awning dry completely before retracting it. Avoid using awnings in high wind or heavy rain. Lubricate arms and moving parts annually with a silicone-based lubricant. Store awnings during off-season to prevent weather-related wear.
What are common body and exterior issues on RVs?
Common issues include:
- Delamination of fiberglass walls due to water intrusion
- Faded paint and decals from sun exposure
- Cracked seals around windows, doors, and lights
- Rust or corrosion on steps, frames, and undercarriage components
⚙️ TIRES, BRAKES & SUSPENSION
How can I prolong the life of my RV tires?
To extend tire life, maintain proper inflation, rotate tires regularly, and store the RV on level ground or jack stands during off-season. Use tire covers to protect from UV damage, and avoid parking on hot asphalt or gravel for long periods. Always follow manufacturer guidelines on load capacity and replace tires after 5–7 years, even if they appear in good condition.
How do I safely inflate and monitor tire pressure?
Use a high-quality digital tire pressure gauge or TPMS (Tire Pressure Monitoring System). Inflate tires to the PSI listed on the RV’s data plate or in the owner’s manual — not the tire sidewall. Always check tire pressure when the tires are cold (before driving). Uneven wear could indicate alignment or suspension issues.
When should I replace RV tires?
Replace RV tires every 5–7 years, regardless of mileage. If you see cracks in the sidewalls, uneven tread wear, or bulges, replace them immediately. Don’t rely solely on tread depth—aging rubber can become unsafe even if the tires look fine.
How often should I check wheel bearings and brakes?
Inspect and repack wheel bearings every 12,000 miles or annually, whichever comes first. Brake inspections should also be done annually or when you notice reduced stopping power, grinding, or pulling to one side. This is especially important for trailers and 5th wheels.
How can I maintain brakes and suspension on trailers?
Regularly inspect brake shoes, magnets, and drums for wear. Adjust brakes according to the manufacturer’s recommendations or install self-adjusting brake systems. For suspension, check leaf springs, equalizers, and bushings for cracks or sagging. Lubricate components and tighten U-bolts if needed. A trailer with poor suspension can cause uneven tire wear and unsafe towing.
💡 ELECTRICAL & GENERATOR
What should I do if my RV’s electrical system fails?
Start by checking the main circuit breaker panel and ensure no breakers are tripped. If connected to shore power, verify that the pedestal is working. For battery power, check the battery voltage and connections. If your RV has an inverter or converter, ensure they’re working properly. If the issue persists, consult a certified RV technician, as electrical failures can stem from wiring, converter issues, or ground faults.
How often should I service the generator?
Most RV generators should be serviced every 100–150 hours of use or annually—whichever comes first. Routine service includes changing the oil and air filter, checking the spark plug, and running the unit under load for at least 30 minutes monthly. Letting a generator sit unused can lead to fuel system clogs and moisture damage.
When and how should I check batteries and converters?
Check your batteries monthly. Look for corrosion on terminals, ensure fluid levels (for lead-acid batteries), and measure voltage. Clean terminals with a baking soda solution if needed. The converter should be checked for proper charging output and cooling fan function. A failing converter can lead to battery drain and power inconsistencies.
Are there DIY options for simple electrical issues?
Yes — you can check fuses, test outlets with a polarity tester, reset breakers, and inspect visible wiring for wear or burn marks. Always disconnect power before attempting any repair. For anything beyond basic checks, it’s best to hire a professional to avoid electrical hazards or voiding warranties.
How do I maintain the shore power connection?
Inspect the power cord and plug before every trip. Look for signs of wear, melting, or discoloration. Use a surge protector every time you connect to shore power. Clean and dry the plug after use and store it properly to prevent damage. Replace damaged cords immediately to avoid shorts or fires.
🌬 HVAC & APPLIANCES
Why isn’t my AC cooling properly?
This could be due to a clogged air filter, blocked return vents, low refrigerant (in some models), or a failing thermostat. Dirty evaporator coils or poor roof vent sealing may also reduce performance. Start with cleaning the filters and checking airflow, then test on a cool morning to see if performance improves. If not, a technician should inspect the system.
What can cause strange noises in my AC?
Rattling or buzzing sounds often come from loose mounting bolts, debris inside the shroud, or a failing fan motor. Squealing could indicate a worn belt or motor bearings. Turn off the AC and inspect the top-mounted unit. If you’re not comfortable removing the shroud, call a qualified RV technician.
How often should RV AC get serviced?
You should inspect and clean the filters monthly and have the entire unit serviced annually. This includes cleaning the condenser and evaporator coils, checking the fan motor, inspecting seals, and verifying electrical connections. Regular service improves cooling efficiency and extends the unit’s life.
Can I run my RV AC on battery/solar?
Typically, RV air conditioners draw too much power for standard battery or solar setups. However, with a robust lithium battery bank, inverter, and high-output solar array, it’s possible—but expensive. Most RVers use a generator or shore power to run their AC.
How do I maintain refrigerator, furnace, and water heaters?
- Refrigerator: Keep vents clear, clean burner tube (if propane), and check door seals.
- Furnace: Inspect intake/exhaust for debris, test the thermostat, and listen for ignition clicking.
- Water Heater: Flush tank annually, clean the anode rod (for Suburban models), and inspect for leaks or rust. Always turn off gas and power before maintenance.
🚰 WATER SYSTEMS & PROPANE
How can I clean or sanitize the freshwater tank?
To sanitize your freshwater tank, fill it with a mixture of 1/4 cup of household bleach per 15 gallons of tank capacity (mixed in water first). Fill the tank completely and run water through all faucets until you smell bleach. Let it sit for at least 12 hours, then drain and flush thoroughly with fresh water until the bleach smell is gone. Do this at least twice a year.
How do I prevent clogs in black/gray tanks?
Always use RV-safe toilet paper and flush with plenty of water. Add tank treatment enzymes to break down waste and prevent odors. Avoid dumping tanks unless they’re at least 2/3 full—this provides enough flow to flush solids. Use a tank rinser or flush valve to clean the black tank after every dump.
What are gray and black tanks?
- Gray tank holds used water from sinks and showers.
- Black tank holds waste water from the toilet.
How often should I flush the water heater?
Flush your RV water heater at least once a year. Remove the drain plug (and anode rod if applicable), open the pressure relief valve, and rinse the tank with a flushing wand. This removes sediment buildup that can reduce efficiency and damage the tank.
How do I inspect propane systems safely?
Do a visual inspection monthly: check for cracked hoses, rusted regulators, and loose fittings. Use a spray bottle with soapy water to detect leaks—bubbles mean gas is escaping. Make sure propane tanks are upright and secured. Have a certified technician pressure-test the system annually.
⚠️ SAFETY & INSPECTION
How do I inspect smoke, CO detectors, and fire extinguishers?
A full pre-trip inspection should include:
- Tire pressure and condition
- Brake and signal lights
- Battery voltage
- Fluid levels (engine oil, coolant, brake, transmission)
- Hitch and towing equipment
- Propane system leaks
- Roof and slide-out seal condition
- Interior systems check (water pump, furnace, fridge, etc.)
How do I prepare for a pre-purchase inspection?
Hire a certified RV technician to do a thorough inspection before purchasing. Make sure the seller allows full access to all systems, including plumbing, electrical, HVAC, roof, frame, and undercarriage. Ask for maintenance records and verify ownership. For private sales, insist on a cold start and full walkthrough.
Why is regular RV maintenance important?
Routine maintenance prevents breakdowns, extends the lifespan of your RV, and protects your investment. Just like a house on wheels, RVs have complex systems that degrade with time, weather, and use. Staying on top of maintenance reduces repair costs and ensures safety while traveling.
What is GVWR and why does it matter?
GVWR stands for Gross Vehicle Weight Rating—the maximum total weight your RV can safely carry, including passengers, gear, fuel, and water. Exceeding this limit stresses your frame, suspension, brakes, and tires, increasing the risk of accidents and costly damage. Always know your RV’s GVWR and calculate total weight before hitting the road.
🛠 COMMON REPAIR ISSUES
What do I do if my roof is leaking?
First, locate the source—look for cracks in sealant around roof edges, vents, or AC units. Temporarily patch with RV roof tape or lap sealant (like Dicor) if you’re on the road. Then, schedule a professional inspection. Water intrusion can damage the ceiling, insulation, and interior framing, so it’s critical to fix it quickly and completely.
How do I fix slideout and seal issues?
Inspect slide seals for cracks, tears, or compression. Clean seals regularly and use slide seal conditioner to keep them flexible. If your slide is misaligned, makes loud noises, or won’t extend/retract smoothly, the motor or gear system might need adjustment or lubrication. Never force a stuck slide—get it serviced to avoid frame damage.
Why is my fridge not cooling on propane?
Possible causes include a dirty burner assembly, blocked flue, bad igniter, or insufficient leveling (absorption fridges need to be level to function properly). Check for a steady blue flame and listen for ignition clicks. Clean the burner with compressed air. If the fridge works on electric but not propane, a tech should check the gas regulator or control board.
What causes electrical outlet failure?
Most often it’s a tripped GFCI outlet. Press the “reset” button on the GFCI outlet (often found in the kitchen or bathroom) and check again. Other causes could be a blown fuse, bad converter, or a loose connection. Use a polarity tester to identify the problem, but call a technician if you’re unsure—RV wiring is complex and improper repairs can be dangerous.
How to troubleshoot AC freeze-ups?
Freeze-ups typically happen due to low airflow or low refrigerant. Check and clean your air filter, ensure return vents aren’t blocked, and make sure the fan is running at the correct speed. Don’t run the AC on low when the ambient temperature is below 70°F. If coils are freezing despite good airflow, it may need professional diagnosis.
