Late year grand wagoneer hits everything except rear locker. They could be had with a trac-lok (limited slip) rear from the factory, but not a locker. However, given they had dana 44's front and rear, there is every manner of limited slip or selectable locker available you can think of. Tow rating is 5000lbs with 750lbs tongue weight and can seat up to 9 in a pinch if you buy a rear facing seat for the cargo area. If well maintained, mechanically they are pretty much bullet proof due to the simplicity and heavy duty components (727 trans, np229 transfer case and d44's front and rear). The np229 is an awd case designed so it can be run full time, but is locked in 4 low.
Electronics can be an issue but it's usually ground/connection (read: moisture) or PO related (see below), not inherent issues in the electronics.
I was in a similar quandary and that's what I landed on. I do have a lot experience with Jeeps and have learned one very important thing regarding reliability and buying one - if you buy one that has been modified, you will have reliability issues. Luckily the GW's are usually ruined far less often than their CJ and wrangler cousins, but beware. I also have a YJ wrangler that is bone stock (you know how hard that is to find now?) except for the exhaust and a warn winch that I installed. In the year+ I've had it, guess what the only thing that went wrong on it was? You guessed it, the aftermarket exhaust...Specifically the exhaust was not aligned properly with the mounts and it put enough stress on it that it cracked the muffler case. If you buy anything modified, be prepared to live with the PO's sins and a less than reliable vehicle.
