I am in the process of a 7x16 toy hauler build. Built a queen bed that folds down from the wall and mounts on e tracks. Also have a bike bar i built to hold 3 motorcycles. Just bought Ikea kitchen cabinets to start putting together. Using all the appliances from a damaged camper. So fridge, stove with oven, sink, and furnace to go in. Will most likely run 2 fresh water tanks, a black and a grey. Also propane and a 12v/120v electric system.
So question is, what did you put in yours and how much does it weigh once finished?
