I've wanted.to do the same, run 2 sperate banks using an isolator and then not having to worry about cycling out the main batteries or draining them and not being able to start the truck. I'm not sure where you are, up here I've always had good luck with MotoMaster Eliminator inverters from Canadian Tire, if you're stateside I'm sure someone here will chime in with a recommended brand.
