Holiday Rambler Invicta Locking Fuel Door — The Part Holiday Rambler Forgot
Your Holiday Rambler Invicta is a premium Class A gas motorhome built on the Ford F-53 chassis. It has luxury finishes, solid engineering — but no fuel door. The gas cap sits completely exposed. The RV Fuel Vault is the exact-fit locking enclosure Holiday Rambler never included.

Why a Locking Gas Cap Is Not Enough
- ✖Your Holiday Rambler Invicta left the factory with a completely exposed gas cap — no fuel door
- ✖The F-53 carries 80-100 gallons of gas worth $300-$400 — one of the largest gas tanks on the road
- ✖Thieves can siphon your entire tank in minutes with a $5 hand pump at any campground or rest stop
- ✖Generic locking caps can be pried off in seconds and offer minimal real protection
- ✖Road grit, salt spray, and fuel splash-back damage your Invicta's premium paint around the exposed filler area
Why a Locking Fuel Door Beats a Locking Gas Cap
- Factory-finished look — eliminates the exposed gas cap on your Holiday Rambler Invicta
- Precision-engineered for the Ford F-53 filler neck configuration used on the Invicta
- Tamper-resistant keyed lock secures your fuel cap in a heavy-duty enclosure
- High-strength fiber-filled polymer — matches your Invicta's premium build quality
- Bolt-on in 8-15 minutes — no drilling, no cutting, no modifications to your Holiday Rambler
- Corrosion-proof construction rated for year-round full-time RV use
