Dynamax Isata 5 Fuel Cap Cover & Locking Fuel Door
The RV Fuel Vault is an armored, patent-pending locking fuel door purpose-built for the Dynamax Isata 5 and its Ram 5500 Super C chassis. Stops fuel theft, siphoning, contamination, and vandalism on your motorhome — the part the factory forgot.
The Problem
- ✖The gas Ram 5500 chassis under the Isata 5 ships with its fuel cap exposed and unprotected
- ✖A full tank of gas sitting in the open at every campground, storage lot, and rest stop
- ✖Sugar, water, or debris in the tank can mean an expensive fuel-system repair and a stranded motorhome
- ✖Factory fuel caps finish with a cheap plastic look that clashes with the Isata 5’s premium fit and finish
The Solution
- Armored, tamper-resistant 3/16″ High Impact Reinforced Material fuel door — direct fit on Dynamax Isata 5 fuel door area
- Patent-pending keyed lock secures your fuel cap
- Bolt-on install in 8–15 minutes — zero modifications, zero warranty-impacting drilling
- Full factory-finished look: replaces the ugly exposed fuel cap with an armored door
- Stops fuel theft, siphoning, and tampering — one armored shield, three problems solved
- Isata 5 setup: 1 small door ($159.95) plus the single-door security screw pack. Limited Lifetime Warranty. Made in Sarasota, Florida.
