i have an 87 3/4 ton. i bobbed the bed a few years ago when i started my project. i took about 10" off. i just got done shortening my frame and taking a 12" section out of the middle of the bed. no more fuel doors. i got ready to start hanging my 2 1/2" flip and i'm going to mount it forward from the stock shackle hanger posistion. i would then be able to take another 6" off the back of the frame. should i re-bob the rear or should i just leave it for later. i will have about 5 1/2" of lift and i am going to run 42's since i haven't gotten to a trail yet i'm just wondering how much dragging it will do.
