Adding a dual battery system for camper

[JoeKan]

Has anyone hooked up a 2nd battery under your hood that is tied in with the starting battery for power for the camper? I've been thinking of doing this and have it "somewhat" figured out but not sure what kind or size of isolater I would need. Any suggestions?
