New & used RV owners
The New RV Owner Checklist
Just bought a motorhome, fifth wheel, travel trailer or toy hauler, new or used? Here is the gear to buy while you are outfitting it, before the first trip.
By The RV Fuel Vault, Sarasota, Florida · Updated October 2026
The one most new owners miss: the fuel fill
Your RV left the factory with an exposed, unlocked fuel cap. Add The RV Fuel Vault while you are outfitting, the same day you buy the surge protector and sewer kit. It bolts on in 8–15 minutes with no drilling, is made in the USA, and starts at $159.95.

Bought a used RV? Check these first
Tire date codes (replace tires older than about 6 years regardless of tread), roof and window seals, detector dates, batteries, and the fuel fill. Sun and road salt crack the factory fuel bezel, and many used coaches have a cap door that no longer latches. A replacement bezel starts at $59.95, and The RV Fuel Vault bolts over it.
First upgrades for a used RVCommon questions
What is the most overlooked item on a new RV checklist?
Fuel security. Most motorhomes, 5th wheels and trailers with onboard fuel ports leave the factory with an exposed, unlocked fuel cap. A locking fuel door such as The RV Fuel Vault (from $159.95) bolts on in 8–15 minutes and protects every tank after it.
Should I buy the essentials from the dealer or separately?
Either works. Buying them with the RV, or asking the dealer to install them before delivery, means you leave ready to camp. Many RV Fuel Vault dealers stock the door; find one at thervfuelvault.com/where-to-buy, or order direct.
Does The RV Fuel Vault fit a travel trailer or fifth wheel?
Yes, if it has an onboard fuel station or generator fill, which usually takes the Round door. It does not fit tow vehicles, cars, or Sprinter, Transit or ProMaster vans.
What should I check first on a used RV?
Tire age, roof and window seals, detector dates, and the fuel fill. A cracked or missing fuel bezel can be replaced (from $59.95) and covered with The RV Fuel Vault.
