Yes. The RV Fuel Vault fits Jayco motorhomes built on Ford Super C, Class C, and Class A gas chassis — from the diesel Seneca to the gas Redhawk, Greyhawk, Alante, and Precept.
Which Jayco models does it fit?
The RV Fuel Vault is engineered for the commercial Ford (and Ram) chassis that Jayco motorhomes are built on. Here is how the lineup breaks down:
| Chassis | Jayco models |
|---|---|
| Super C (Ford F-550 / F-600 diesel) | Seneca, Seneca XT |
| Class C (Ford E-450 gas) | Redhawk SE, Greyhawk XL |
| Class A gas (Ford F53) | Alante, Precept |

Why Jayco owners need it
Whether you tow with a diesel Seneca or travel in a gas Precept, the fuel cap on your Jayco sits exposed on the side of the coach with no factory lock. A full tank can hold hundreds of dollars in fuel — and a few dollars of sugar or water in the tank can mean a five-figure repair. The RV Fuel Vault locks it all away.
- Stops fuel theft & siphoning — a keyed, virtually unbreakable door over the cap.
- Prevents contamination — no more open access to add water, sugar, or the wrong fluid.
- Built tough — 3/16″ fiber-filled polymer that is non-corrosive and resists prying.
- Factory-finished look — covers the ugly exposed cap for a clean, finished appearance.
