FJ's seem to be very trouble free from my personal interaction with owners. I know 4 people with them and all of them wheel them. They aren't "mall crawlers". People who "break", don't just "break". Look. The bottom line is not what you drive,
it's how you drive it. But more often than not, folks who drive Hummers, think they can go anywhere. Those are the ones I avoid like the plague on the trails, maybe a "hi", but pretty much a "stay the **** away from me" on the tracks.
A member of my Jeep club put up with this love muffin in an H1 for the duration of a wheeling trip. It defied and went well beyond "ribbing". Anywho, the H1 love muffin, was stuck up to his hubs in mud. My buddy grenaded 1st, 2nd, 3rd and Reverse of his 2000 TJ. But he extracted the H1. Not many can lay claim to that. H2's are a joke to begin with.
I've never been stuck. The closest I got, was on my clubs SnoFari in 2007 at West Branch in January. Not much snow, but tank traps galore. I had my 83 CJ7 at the time. I entered the first hole straddling the right side and my drivers door dipping below the top of the water. I thought my Dana 300 was engaged, but I went 3/4's of the way through in 2WD, which was a feat in itself. My read was perfect, but the gears didn't "mesh" good enough. I nudged a buried boulder with my front diff, cover. I stop, back up about 10 feet and engage the 300. By this time, one of the more accomplished people in our group said "Pull your cable, you're done!" I put her in drive and drove out to everyone's amazement.
Jeeps are an excellent off road vehicle. But, the Early Bronco's and the Mid 90's D90/D110's are tops (hell, the Camel Trophy vehicles were stock Discovery XD's with a roof rack and lights). I'd even put the old FJ40's up there too. People buy different vehicles, for various reasons. But I can make substantiated, non-biased/opinionated arguments for those 4 vehicles being "the best". It is even voiced by John Cappa himself: "The Early Bronco is the greatest 4wd vehicle ever". I've met him in person and we have discussed this in length. We had some visitors on our run, that traveled from a Swedish 4wd Magazine.
Here is a custom 4 door Tracker that can best any Rubicon I've seen in person. 18" Travel Fox Racing shocks all around. He has since rolled it and instead of Dana 44's F & R, he's going with 60's.
He is a Trail Guide (Trail Leader not a Sweep) on our Club Run. We are now getting National Attention. Our Club maintains 60+ miles of ORV trails twice a year and put on the most consistent GLFWDA Event. We've only been around since Nov. 2005 on top of it. But I cannot knock another man's ride, I just don't prefer Hummers.
