2016–2027 Jayco Seneca Locking Fuel Door
The RV Fuel Vault is confirmed to fit the Jayco Seneca on the Freightliner S2RV chassis. Here are the covered floor plans and the exact parts for your rig.
Covered floor plans
Freightliner S2RV chassis uses single-point diesel fueling (one large exposed fill) — same configuration as the NeXus Wraith. Mapped to the RVFV Large door provisionally (verified=false); confirm exposed cap vs. builder-installed recessed fuel door from a photo. If recessed, use Large bezel RVFVB-9002L instead of the door.
