Freightliner S2RV Super C Fuel Door Replacement
Super C motorhomes on the Freightliner S2RV have one large exposed diesel fill. The large RV Fuel Vault door (RVFV-1002L) with SS100 security screws bolts over it in 8–15 minutes and locks.
Why a Locking Gas Cap Is Not Enough
- ✖The S2RV diesel fill sits exposed with no locking door
- ✖A large diesel tank is a valuable siphoning target at storage lots and truck stops
- ✖Water or debris in diesel can mean costly fuel-system repairs
Why a Locking Fuel Door Beats a Locking Gas Cap
- Large door RVFV-1002L + SS100 security screws — the S2RV fit
- Uses the factory screw holes — no drilling or cutting
- Keyed lock; factory cap stays in place
- Limited Lifetime Warranty and $500 No-Siphon Promise
- Made in the USA
