'96 full time 4wd NP249, 318 motor. I dont remember the axle ratio, but I ordered a build sheet from Jeep, and it says rated to tow up to 6500 lbs. I am looking to tow an 19', inboard open bow family type boat, I think it weighs about 3500 lbs. I just wonder what others experience towing is. Frankly, the motor doesnt feel all that peppy. The jeep only has 86,000 miles on it.
should have no problem towing a 3500lb boat/trailer. i used my ZJ to tow a 1969 pontiac grand prix on a uhaul car trailer (~6000lb total). not bad at all, helps alot to turn off overdrive and when taking off from stoplights, start in 1st or 2nd gear.
Reliability is relative
Been towing my 21' open bow inboard v8 single axle trailer with surge brake for several years now, never had any issues whatsoever, load of kids ac on high. It tugs the rig out of the steepest ramp no problem, never had to use 4lo, it's got a 3.73.
I towed a 21' Four Winns for years with my ZJ and it's only a 4.0. To make it tow better I added a B&M Supercooler, Bilstein monotube high pressure shocks, Air Lift air bags in the rear coils, LT rated tires and better quality brake rotors. And I added surge drum brakes on the trailer. Your 5.2 V8 should have no problem with that boat if the Jeep and trailer are set up right.
