You'd think Bass Pro Shops would have something for a dual battery set-up like you're wanting...

A lot of racers use this as well. You can get dual battery switches but they only let an AGM battery charge to about 80%. The DC-DC Isolators let both batteries charge to 100% but don't seem all that adept at switching big current in the event a jump was needed ot the primary. At least not the ones I have run across but I'm just learning about them.
