Well damn, My TJ is a 2000 and I've been crawling over and under it enough to know these things inside out. I'm not quite sure what you mean by "One is listed as a J-10 and the other is a Comanche", J10 and comanche are completely different model that have been discontinued for quite some time now. J10 is the full size truck whereas comanche is the smaller pickup based on cherokee.I have a hardtop, but my buddy who used to have an YJ told me softtop is absolutely doable in winter, and I have seen people do that. 2000 and before use canva for soft top, 2001 and after use sailcloth which is stronger and quieter. Take note if the softtop is original or aftermarket, some aftermarket are good some are crap. Just a thought, softtop is easier to aquire afterwards and there are quite a few selections, but hardtop OEM is the best.Here's something about differences in model year: http://www.geocities.com/jeepboy49028/changes.html
Quitcher whinin. When I was a kid, they didn't have tops, and we had to bore through solid ice with our teeth driving down the ice age freeway. We didn't even have wipers for the windows, we had to use our armhair to wipe the mastadon poo off the windshield.
I thought they redesigned the head in 2000 to fix the problem, or was it 2001?Axle strength is part of the reason, d35 usually come with 3.07 gear ratio whereas d44 is 3.73, which is much handier with larger tires. Besides, locker is always handy, if I had one I wouldn't have gotten stuck in front of my driveway this winter. 31" is the biggest you can fit on stock suspension by the way.Nutsak are you on jeepforum by any chance?
