Coachmen experts recommend regular inspections of critical RV systems, including electrical, plumbing, and engine components, to ensure safety and longevity. Key practices include checking tire pressure, testing smoke detectors, sanitizing water tanks, and lubricating slide-outs. Seasonal maintenance, such as winterizing pipes and cleaning air conditioning units, is also essential to avoid costly repairs.
How Often Should You Perform Routine RV Maintenance Checks?
Perform visual inspections before every trip, including tire pressure, fluid levels, and brake functionality. Comprehensive checks—such as roof sealant reviews, generator testing, and appliance diagnostics—should occur monthly. Coachmen technicians emphasize biannual professional inspections to assess hidden issues like chassis rust or propane system leaks.
For optimal results, create a maintenance checklist divided into three categories: pre-trip, monthly, and seasonal. Pre-trip inspections should take 15–20 minutes and include verifying all lights function properly, testing emergency brakes, and ensuring hitch connections are secure. Monthly checks require 2–3 hours to inspect roof seams with a UV-resistant sealant, test carbon monoxide detectors, and clean refrigerator coils. Seasonal maintenance aligns with weather changes—spring is ideal for de-winterizing systems, while fall focuses on antifreeze applications. Coachmen’s mobile app offers digital tracking tools with reminder alerts for oil changes (every 3,000 miles for gas engines) and generator load tests (every 50 hours of runtime).
What Are the Most Overlooked RV Maintenance Tasks?
Commonly neglected tasks include sanitizing gray water tanks, recalibrating slide-out gears, and replacing HVAC filters. Owners often forget to inspect awning fabrics for UV damage or test emergency exit seals. Coachmen’s repair logs show that 43% of warranty claims stem from poor roof caulking maintenance, a quick but critical task.
Three often-ignored areas warrant special attention. First, wheel bearings require repacking every 12,000 miles—failure to do so increases brake failure risks by 60% in mountainous terrain. Second, window and door seals degrade silently; perform a dollar bill test annually—if you can easily pull a bill from closed seals, apply new butyl tape. Third, water heater anode rods need replacement every 6–12 months depending on usage. Coachmen’s study found that 68% of tank corrosion issues trace back to depleted anode rods. A simple table illustrates critical overlooked tasks:
| Task | Frequency | Tool Required |
|---|---|---|
| Wheel Bearing Service | 12,000 miles | Grease gun |
| Seal Integrity Test | Annually | Moisture meter |
| Anode Rod Replacement | 6-12 months | Socket wrench |
Why Is Tire Maintenance Critical for RV Safety?
RVs carry heavy loads, making tires prone to blowouts if underinflated or aged. Coachmen advises checking pressure when tires are cold, rotating them every 8,000 miles, and replacing them every 5–7 years regardless of tread depth. Use a TPMS (Tire Pressure Monitoring System) to detect leaks early—a 10% pressure drop increases sidewall stress by 30%.
How Do You Winterize an RV’s Plumbing System?
Winterization involves draining freshwater tanks, blowing out pipes with compressed air, and adding antifreeze to traps. Coachmen’s protocol specifies using non-toxic propylene glycol solutions rated for -50°F. Critical steps include bypassing the water heater, emptying black tanks completely, and lubricating dump valves to prevent freezing-induced cracks.
When Should You Replace RV Batteries?
Replace deep-cycle RV batteries when their capacity drops below 80%—typically every 3–5 years. Signs include slower appliance startup, voltage drops below 12.4V when idle, or swollen casings. Coachmen recommends lithium-ion upgrades for frequent travelers; they last 8+ years and charge 3x faster than lead-acid models.
“Most owners focus on mechanical systems but ignore the RV’s ‘skin.’ Inspect exterior seams annually with a moisture meter—trapped water causes 70% of structural issues we see. Also, modern RVs have complex electronics; update control firmware quarterly to prevent glitches.”

Conclusion
Coachmen’s maintenance guidelines blend scheduled inspections with adaptive care for evolving RV technologies. By prioritizing tire health, plumbing winterization, and battery upgrades, owners can extend vehicle lifespan by 8–12 years. Document all services in a logbook—this boosts resale value and helps technicians diagnose recurring issues faster.
FAQs
- Does Coachmen Recommend DIY or Professional Maintenance?
- Simple tasks like fluid checks or exterior washing suit DIY. Leave electrical diagnostics, brake adjustments, and roof repairs to certified technicians to avoid voiding warranties.
- Are Synthetic Oils Better for RV Engines?
- Yes. Synthetic oils withstand extreme temperatures better, extending drain intervals to 15,000 miles versus 7,500 for conventional oils. Coachmen approves SAE 5W-40 synthetic for most diesel pusher models.
- How Long Do RV Roof Sealants Last?
- High-quality lap sealants (like Dicor) last 2–3 years. Coachmen uses thermoplastic roofing on newer models, which requires silicone-based sealants every 5 years. Inspect after hail storms or branch impacts.
