This is a 21 ft living quarters box. It needs to be finished , we were going to make a motor home. This would be great on a military 6x6 for an off grid beast or a toy hauler . The box is 17 ft on the lower part and 4 ft over the cab It has a 16 ft slide out on it. I have a bunch of new parts like Windows for it . It's probably worth $1000 in aluminum scrap alone. So make me an offer I need it gone. We can load it on your trailer if needed. If you want a truck to put it on see my other add. Thanks
