I did not get the towing package with my rig. What all do i need besides the obvious stuff? (i.e. hitch and wiring harness). I am planning on regearing to 5.13's for future 35's. Right now and until I've saved up, i have 265's and am wondering how this setup will ride. I've seen several threads with towing in auto's but nothing much on manuals. Any input would be grateful.
