Thats a good looking truck you got there...

My 36 (chevy) was about 60" up front and about 80" out back. But you can narrow up the rear by dropping the outside rears off. I brought mine home on a dual axle trailer loaded it with the front forward that way the rear axle didnt need to get past the fenders.. cause it wouldnt have made it...

as far as the weight goes.. id be guessing.. especially with the dump bed on it...
