Before You Go: RV Trip Essentials

Dump stations are only one piece of the trip puzzle. Before you set out for your trip to Caldwell, Idaho, it's worth taking thirty minutes to check that the basics are in place — the four areas below are where unprepared RVers most often get stung.

Check your RV insurance coverage

A standard auto policy rarely covers a Class A, Class C, or travel trailer the way a dedicated RV insurance policy does. If you're financing a motorhome, lenders typically require comprehensive and collision; full-timers should additionally price in vacation liability and personal belongings coverage. Rates vary widely by state and travel pattern — compare quotes from multiple RV-focused carriers before each season.

Know your roadside assistance options

RV-specific roadside plans tow motorhomes and trailers that regular AAA coverage won't touch — flat beds, mobile mechanics, tire service for duallies, and even emergency lockouts at remote campgrounds. Good plans cover your spouse and trailer even if you're driving a separate vehicle, and some include trip interruption reimbursement if a breakdown costs you a reservation.

Decide about an extended warranty early

Original manufacturer warranties on new RVs typically run 12–24 months — shorter than most buyers realize. An extended service contract (essentially a mechanical breakdown policy) covers the appliances, slides, levelling systems, and drivetrain components that can run $3,000–$10,000 to replace. The time to price one is before the factory coverage expires, not after something breaks.

Set up a travel rewards card for fuel and fees

A no-annual-fee travel or gas rewards card pays for itself on a single month of RV travel. Expect to spend $400–$800 per week combined on fuel, campgrounds, and propane — 3–5% cash back on gas alone covers the next oil change. For bigger trips, a sign-up bonus can offset campground fees for the whole season.
