Thanks, it is a second series 55 with complete suspension upgrate from a later model 3/4 ton truck. Engine is a 455 olds and th200 4r which has been built to stand the added pressure of the big block olds and towing. frame was added from another 55 chassis I bought just for that purpose, it has been plated at all four joints and double welded. Also added air helpers in the rear so it could pull a little more weight, already has the electric brake system installed and a weight dist. hitch too. I would like to have something in the 32 to 36 foot range.....
