Thanx, this is about what I figured. It's an '03 TJ w/ Dana 44 rear, Ox rear locker, Rubicon Express 5.5" suspension lift, Old Man Emu shocks and steering damper, tail shaft conversion w/ slip joint eliminator, 35" BFG MT's, American Racing black steel wheels, Warn f/r bumpers w/ swing away tire mount (spare same as on all 4 corners), Warn winch w/ wire cable (no nylon cable yet), rear seat removed and full trail roll cage, regeared to keep up w/ the big tires. I figured 3500 lbs. w/ all this stuff, maybe slightly heavier. So if we keep the trailer to under 1500, then we don't exceed max towing, but is pulling 5K #'s likely to cause any strain/excessive wear if we drive sanely? Appreciate comments here. Don't want my X to suffer for the sake of saving highway miles on the Jeep. It seems to break down frequently on his 250 mile trips between home and college. Around down the thing seems happy, but 3 hours at Interstate speed always seems to crap something out (recent breakdowns include x-fer case, driveshaft bearings, etc.). I think it is too modified for an everday drive, except for short around town jaunts, but the Interstate is definitely out.
