The pic posted is an Amerigo 11.6. It probably has the tilt out snap n nap in the back which allows for 6 sleeping people. I currently own and I am renovating this exact camper. It is made for a 1 ton 3500, 8 foot bed. It is very very heavy. Approximately 2700 pounds dry. Most were built in the 70's and re introduced for just a couple of years in the 90's. They are very sought after for those interested in a very unique vintage camper. Built like a whale. I know almost every inch of these models. I personally love them, for the mere fact they have a full 1 piece fiberglass roof and front wrap around fiberglass cab over.
