Immobilizer for Class A motorhome.

Please tell us what motorhome you have. That will make a significant difference is suggestions.

I can disable the engine on my Workhorse by simply pulling a plug... Now the catch is I'm not going to tell you which plug. but if that plug is pulled it will crank all day (or till the battery dies) but no start.. And no damage.

Previous owner installed an alarm system on this MH that disables the ignition if triggered. Never use the thing but looks like major hassle to remove.

I haven't felt the need to use it, but a previous owner installed a matching switch in a blank spot on the existing dash switch panel that's just labeled "Accessory". Turning it off disables the fuel pump relay. I did test it though, and it does disable the coach quite effectively as expected.

I saw your other post about a GPS tracker - do you park your RV in downtown Philly? What sort of security outside of a locked door and removing the keys are you looking for?

How about a simple battery disconnect switch on the chassis battery?
What exactly is your goal, for the rig to not start or, not to be able to move when it does start?
