Fifth wheels are covered under travel trailer policies: $400�900/yr typically. Full-timer coverage (living in it) is higher. Your tow vehicle policy does NOT cover the trailer � you need a separate policy. If the fifth wheel is financed, the lender will require comprehensive coverage. Shop RV-specific insurers like Good Sam or National General.

Wheel bearings should be repacked every 10,000�12,000 miles � this is the #1 deferred maintenance item on trailers and causes catastrophic failures when neglected. Annual electric brake inspection. Slide-out seals same as motorhomes. Fifth wheel coupling (king pin, slider) needs lubrication. Annual roof and sidewall seal inspection and reseal ($200�500).

The biggest hidden cost: your tow vehicle. A fifth wheel rated at 16,000 lbs GVWR needs a capable 1-ton pickup � if you don't have one, budget $30,000�60,000 for the right truck. The pin weight alone (weight on the hitch) is typically 15�25% of trailer weight. Don't underestimate this � it's a safety and vehicle warranty issue.

Check NADA guides and RV Trader for current market prices. Depreciation is steep � a 3-year-old unit is often 35�45% off MSRP. Use deferred maintenance (bearing repack, seals, roof, brake inspection) as negotiation points � each has a real, documentable cost. The coupling system (king pin wear, slider function) is specific to fifth wheels and repairs cost real money.

Same water damage red flags as motorhomes � soft floors, ceiling stains, delaminated walls. Neglected wheel bearings (common and can cause a wheel-off at highway speed � dangerous). Tires with good tread but old DOT dates � dry rot is invisible until a blowout. King pin wear that creates excessive play in the fifth wheel coupling.
