One question, has anyone tried to siphon gas from one of the RVs (if that is the reason for a locking gas cap)?
I can attest to the fact that, at least for this non-talented thief, there was absolutely no way I could get ANY type of hose, pipe, or other device in the gas tank.
I had some bad gas, and needed to drain the gas tank, and finally had to unhook the gas line from the generator to get the gas to drain..
I had never put much stock into anti-siphon devices, but, the gas line and tank on our VEGAS made a believer of this boy.
