I don't particularly care for the Wranglers, they're overpriced, and over-rated really, you can put a knowledgeable driver behind the wheel of a Bronco 2 and do the same thing as a Wrangler. People overprice and of course all the wheelers have made the Wrangler into a toy so the cost of purchasing one and parts, and accessories ridiculously high.
I had a 96 Jeep Grand Cherokee Limited Edition with the 4.0L Straight 6, 4 speed automatic transmission and full time 4WD. I can say this it was bone stock, ok I did have an ARB Bumper on the front but other than that no other modifications. That Jeep went places with standard all season tires you wouldn't think of going. I was amazed how well the full time 4WD system transferred power, and pulled the jeep through some pretty nasty situations. I took it places that I didn't think it would go, but it surprised me every time. Towed a 93 ford ranger 4x4 from Sacramento California back to Idaho and still averaged around 17mpg on the highway, and went through Nevada in the middle of summer towing that ranger in temps over 100 degrees, engine never got hot, ran the air conditioner the whole time without any issues, plenty of power and torque. Hauled a 1983 Ford Full Size Bronco on my car trailer with my Jeep about 40 miles over 6500lbs total weight with trailer, and Bronco, was able to easily maintain highway speeds 65mph and could still go faster if I wanted. That 4.0L Straight 6 was a great engine, never had any transmission problems and had 232,000+ miles on it when I sold it, its still on the road and the new owner lives up in the mountains about 70 miles from where I live, he loves it in the winter time, it does awesome in the snow/ice.
Like I said I don't care for the Wrangler, but the ZJ and the XJ's aren't that bad of a vehicle really. Most issues I have seen are people who have modified their Jeeps, who end up having drive train problems which when you are trying to spin 33"+ tires with stock drive train something is gonna break doesn't matter which brand of vehicle you have, ok well take that badk if you do that on a Bronco 2 you won't really break anything it don't have the power at that point to break anything LOL. That being said the Bronco 2 is extremely capable as well in the right hands. Personally I wouldn't wheel with a Bronco 2, or a Jeep Wrangler just because I'd be the only dumb ass on the trail to flip over LOL. However, the larger and wider vehicle's I don't mind wheeling in occasionally. I don't really wheel at all anymore because I can't afford the gas and if something breaks I'd be screwed.
