Skip, It all started out with wanting to add a hitch to pull a 10,000lb trailer. After reading many posts relating to hitches, their capacities and cracked engine cradles, I wanted to take no chances. After studying the structure of the bus I designed a structure that ties into the engine cradle, roof structure and sign board. It turned into a bigger project than I thought in that it involved removing all the rear skins and rear structure. See pictures. From there I extended the engine cradle and added the rest of the structure. Just as it was barely completed, we took off for Sturgis SD (2500 mile round trip) with a 7,000lb trailer. Trailer pulled like a dream. The rear structure is also designed to add a lift for my Harley (900lbs) to hang off the back of the bus. The 900lb, $20,000 Harley was probally my biggest concern for doing it my way.
