In answer to the question about cutting it off at the rear crossmember, you would have to remove the wood body before you could cut or unbolt the frame add on and accomplish anything more then making it a taildragger.

The whole shell is wood, including a plywood floor covering everything behind the front seats. I'd expect it to weigh 6,000 -7,000 lbs without the camping stuff.

Sorry I miss read your original post. Gene
