I'm hoping for some seasoned advice, good idea's, criticism, and general thoughts on my plan. Looking at the Somerset E3 "toy haul" edition. We are planning to modify and equip it and tow vehicle with the needed equipment for long term boondocking. Solar on roof, Lithium Iron Phosphate (Battleborn) batteries, replace inside toilet/shower with expedition style 12 v fridge freezer, toss factory fridge (more storage) use composting toilet along with continuous hot water shower in stand alone pop up room, 65 gal. water bladder and 3 stage filter system w/12 volt pump. Upgrade axle, heat shields, fantastic fan, outdoor cooking area, pillow top foam mattress covers. This set up needs to accommodate 3 adults. Any thoughts, idea's, suggestions? Thanks!
