Just wondering about body flex while driving you can look throught your rear view mirror and notice when you go over bumps the cab and box jumping around, when you watch trucks from a distance you dont notice at all . I was just interested in hearing some comments on body flex from other pickup owners, i think i get it worse on my truck because of my regular cab and 8 foot box. granted it is alot less than my 89 was. My guess is that they can not build a truck strong enough that has a one piece cab and box on the frame, would also like to know how much flex is normal. I also never carry loads over capacity. Thank you.
