Workhorse W20 Locking Gas Cap

NAPA Part Number 703-1689 Locking Gas Cap fits the W20 Chassis on my Motorhome.

I have been wanting to add a Locking Gas Cap, not so much as to prevent siphoning, but to stymie anyone from contributing anything but Gas to the tank.

    After my fiasco with putting DEF in my fuel tank, I put also put on a locking gas cap. It slows me down and makes me think, and prevents others from making a mistake or deliberately causing damage.

    When I ask about a locking cap for my W-22, they said "Chevy Silverado will fit" and the man talking to me also drove a W-22 on occasion.

    And fit it did.

    Alas, today it's defective (lock broke) but it still LOOKS like a locking cap so thieves move on cause if there are 20 RV's parked there, why cut a hose when you can pull a cap?
