Looks like if I make mine 7' it will be a tad narrower than normal. That is fine with me, I was just curious as to how would it will be.
I would like to keep my truck as narrow as possible. A new f250 single rear wheels is also 7' overall on the pickup bed, so my truck with duals will be the same width as a new single wheeled truck.
