Isolate camper power from truck power

What do I ask for at a RV supply store to isolate my truck batteries from my camper battery. I accidentally left a light on in the camper & drained the camper and both truck batteries. My neighbor told me to get this installed a year ago but foolish me I had to drag my feet and now I'm busy charging batteries

I would probably just go w/ a 70A relay between the feed from the truck and the camper batteries. Drive that off our Truck "run" circuit, so the two are only connected when the key is in that position, and the Alternator is likely charging.

This is a $12 fix, unless you want to be able to jump the truck off the house battery.

I use a blue seas ACR (automatic charge relay) that way it only is connected when the truck is running ... And when my camper is on charge it will charge the batt in the truck aswell

Were you able to wire up your fuse box so that you could plug the relay right into an appropriate spot or did you have to go the route of cutting wires and wiring a relay socket?
