Don't mistake what I am saying. I agree that you should go by manufacturers specifications as far as towing capacities go. I would never recommend to anybody to tow anything over the vehicles rating. If you do you definitely open yourself for a lawsuit if an accident happens. Basically the bottom line is match your truck to your trailer or vice versa. And I do believe a regular cab long bed and an extended cab short bed are the same chassis. I don't believe, but I could be wrong, That anyone makes a regular cab, short bed, 1 ton truck.And by the way Pete your truck is cool.
