Seems the more research I do the more unsure I become. Here's the deal we are currently at Phase 1 under 12v power but are about to make the move to Phase 1.5 and expand the system. Prior to slapping a couple panels on the lid I am wanting to add an inverter and shore power. With winter on the way I want to take greater advantage of our favorite mountain resort with plug ins and an indoor pool. In general we don't have a lot of AC need and other than our winter weekend getaway we rarely camp near 110. But after 1 season with just light and heat we are look forward to making the mornings brew, keeping the coldies cold (Norcold 751) and maybe making some warm slop for the childrens. Here's my dilemma? Do I divide and conquer with separate units, inverter and charger, or spend a few extra bucks and buy an inverter/charger? It seems everyone has a different way to skin the same cat. What am I missing? Your thoughts and witty barbs appreciated.
