RV Maintenance & Repair Guides

Available guides

More guides are added weekly. The category is organized by system — plumbing, electrical, propane, appliances, slide-outs, awnings, and chassis. Use the system categories to navigate or search for specific problems.

Plumbing & tanks

  Why it happens, what actually works to clean sensors, current parts costs, and when to switch to external sensors.
• RV Black Tank Flush: Step-by-Step Procedure
  Proper flush technique, built-in vs tank rinser wand, what NOT to put down the drain, deep flush schedule.

• Propane Regulator Replacement
  Diagnosis, 30-minute swap procedure, leak testing protocol, current parts cost. Yellow flames + weak heat = regulator 95% of the time.
• Fresh Water Pump Replacement
  Failure diagnosis, GPM/PSI sizing, accumulator tank decisions, and Shurflo vs Flojet vs budget alternatives.

Electrical

How FixForge RV coverage is organized

RV systems break down differently than residential systems — a residential plumber is rarely a useful resource for an RV plumbing problem because the materials, pressures, and operating conditions are different. Our RV guides assume you're operating a typical Class A, Class C, fifth wheel, or travel trailer in normal use. Where guidance differs for diesel pushers, off-grid boondocking setups, or vintage Airstream rebuilds, we say so explicitly.

Every RV guide includes a "When to stop and call a pro" decision point. We are not in the business of getting you hurt or destroying your equipment to save a service call. Propane work above the regulator, 120V high-amperage electrical, structural delamination repair, and slide-out hydraulic system disassembly are categories where DIY without specific training causes more expensive problems than it solves. We say so in those guides.

Costs reflect 2026 prices

Part prices and labor estimates in RV guides are current as of the Last Updated date in each guide's header. RV part pricing moves more than most categories — supply chain shifts, manufacturer changes, and seasonal demand all affect costs significantly. We update guides quarterly or when a price moves more than 15% from the cited range.
