I have a 4x2 4.2l with a 3.31 rear axel (must have been changed by previous owner). Automatic with the tow/haul button and tranny cooler. 6.5' box. What capacities am I limited to with a hitch or 5th wheel? I have no owners manual. Thanks in advance for some help.

Well forget about a 5th wheel in a 6.5 foot box unless you use a slide mount and a very small light weight 5th wheel special.
A std. cab with you motor size and 3.31 is 4700 lbs or 9000 gross combined weight.
Reference page 192 of 02 owners manuel.
Good luck.
