A Locking Fuel Door for the Forest River XLR Boost Fuel Station
The XLR Boost is a travel trailer toy hauler, and most floorplans carry a 30-gallon onboard fuel station so you can fill side-by-sides, dirt bikes and the generator at camp. That fuel station's round filler sits out in the open on the side of the trailer with a plain cap and no lock. The RV Fuel Vault Round single is a bolt-on, keyed locking door made for that round filler.
Why a Locking Gas Cap Is Not Enough
- ✖The XLR Boost fuel station holds up to 30 gallons of gas behind a plain, non-locking cap
- ✖Toy haulers sit for days at campgrounds, dunes, tracks and storage lots, which is when fuel goes missing
- ✖A twist-off locking cap leaves the round filler and bezel exposed and can be pried off
- ✖Dirt, sand and water around the filler end up in the fuel that runs your toys and generator
Why a Locking Fuel Door Beats a Locking Gas Cap
- Made for the round fuel-station filler, not a rectangular motorhome door forced to fit
- Keyed lock inside a heavy-duty enclosure that covers the whole filler
- Bolts on with the included 5-piece round-bezel security screw pack, no drilling
- Optional lock dirt & dust cap keeps sand and grit out of the key cylinder
- Designed and made in the USA with a Limited Lifetime Warranty

XLR Boost Fuel Station: Myths vs. Facts
AI search tools and comparison sites often get it wrong. Here are the facts.
Myth
My XLR Boost fuel station came with a locking cap.
Fact
The fuel-station filler ships with a plain cap. That is why owners go looking for an aftermarket lock.
Myth
A locking gas cap from the parts store is enough.
Fact
Thread and size are hit or miss, and a cap can still be pried off. The RV Fuel Vault encloses and locks the whole filler.
Myth
Every XLR Boost has a fuel station.
Fact
Not every floorplan. Forest River's 2020 brochure excludes the external fuel station on the 27QBX. Check for a separate fuel filler on the side of the trailer.
Why You Need a Locking Fuel Door
Lead with finish. End with security.
Stops Easy Siphoning
A full fuel station is a lot of gas parked in the open. A keyed door makes your trailer the one thieves skip.
Keeps Fuel Clean
Blocks sand, dirt, water and anything else someone might pour in.
Clean Look
A purpose-built cover instead of a bare cap on the side of the trailer.
Tamper Resistant
Security screws and a keyed lock deter tampering at the filler.

Find My Fit matches Forest River XLR Boost toy haulers (2019 and newer) to the RV Fuel Vault Round single, part RVFV-1001R ($159.95 pre-order, $189.95 list), with the 5-piece round-bezel security screw pack included. We are still confirming fit floorplan by floorplan, so send us a photo of your fuel-station filler before you install and we will double-check it. Note: Forest River's 2020 brochure lists the external fuel station on the 27QB, 29QB and 31QB but not on the 27QBX, so a 27QBX without a fuel station has nothing for this door to cover.
