Truck and camper together weigh 4270, putting the camper alone at about 1350. That gives me about 1000 lbs to work with to keep it under gvwr of 5100. The only suspention mods thus far are timbrens which boosted the tail up about 3". I also lengthened the frame about 2 feet to give some support to the back end and give me a better location to bolt the bumper on. Unfortunately, it's a short bed truck, but it's what I had, so it's what I used! Sink, stove, heater, and most of the windows were all salvaged from old campers. The wood burner (about 100 lbs) is really overkill, as the propane heater would do fine all by itself. I saved weight by not putting in other "luxuries" like a forced air furnace, extra 12v battery, generator, hot water heater, refrig, toilet, shower, etc. Only one cabinet, and all the rest of the storage is either on a couple of shelves, or under the bed/couch.... Thanks for the help with the pics!
