Does The RV Fuel Vault cover both diesel and DEF on my Accolade XL?

Yes. It covers and secures both the diesel fuel cap and the DEF cap in one armored enclosure.

Will it fit every Accolade XL floorplan?

Yes. Every Entegra Accolade XL is built on the Ford F-600 chassis with the same filler configuration. Fits all floorplans.

What is the difference between the Accolade XT and XL versions?

The Accolade XT is on the Ford F-550, the XL is on the larger Ford F-600. The RV Fuel Vault has specific fitments for both chassis.

How long does installation take?

8-15 minutes with basic hand tools. No drilling, no cutting.

Limited Lifetime Warranty plus a 30-day satisfaction guarantee.

Built for the Accolade XL

Entegra Accolade XL Locking Fuel Door — Armor for the Biggest Entegra

The Entegra Accolade XL is the ultimate Super C — built on the Ford F-600 with the 7.3L V8 gas or 6.7L Power Stroke diesel. But even at this price point, Entegra left the fuel caps completely exposed. The RV Fuel Vault is the exact-fit locking enclosure the Accolade XL deserves.

Why a Locking Gas Cap Is Not Enough

✖Your Entegra Accolade XL left the factory with exposed, unlocked fuel caps — no fuel door
✖The F-600 chassis carries a massive fuel supply worth hundreds of dollars — a prime theft target
✖DEF contamination from tampering can destroy your SCR system — a $5,000-$10,000+ repair
✖Cheap locking caps are easily defeated and only cover one filler at a time
✖Road debris and diesel splash-back damage your Accolade XL's premium paint finish
