Inverter in tow vehicle

Yepper ,,, Good ideas here. I like to tinker and already have this pure sine wave inverter just sittin in garage. I like the idea of connecting to TT shore power and also toppin off the 2 deep cycle batterys. I might even surprise the wife and get one them electric coolers or mini frig. and put in back seat deck area of the truck and not mess with bags of ice. And maybe even get the wife thinkin this project is for her convienence and connectin to the TT just happens to be a 2nd thought !!!! AND ,,, i could tell her this is all younses ideas of how I can clean up the garage and make use of this inverter that she says just keeps siitin round in the way of things !!!!
