My two cents: you could need a 12 volt relay/contactor controlled by the ignition switch (a starter solenoid could work) . With the ignition on, the contactor could connect the battery to your RV through a circuit breaker/resettable fuse located near the truck's battery. I would run AWG 8 gauge conductors from the contactor and battery negative to the truck's rear end to compensate for voltage drop due to the distance. Just saying.
