This is an 06 mega cab stretch I came across in Ohio this past weekend. The owner said he bought it used with 19k miles and had his five sons help him cut in in half in a day, much to his wife's disapproval. He stretched the frame 27-3/16", and fabricated a new roof and floor pan so as not to have any welds in the roof or floor, and uses it to pull his 5er. The truck had Michigan tags, and the owner said he builds tractors for pulls and did this as a transport vehicle to the tractor pulls.
