Just joined, first post, couple week old thread, I'll try to make it worth it.........
Currently have a 1998 Grand Cherokee. The 4.0 GC is reliable, gets decent MPG's (19-20 backroads, 18 interstate, both with 2" lift and 31's) and is down right easy/cheap to fit 31's on. Rear axle is the weak point but fine if you keep it open and stick to 31's. On paper it's only slightly larger than the Cherokee in the real world it's much better on anyone riding and more storage. The Cherokee is gone the GC isn't. It's also a better vehicle than the ZR2 pickup I used to have. Not the electronics mind you. Chrysler electronics have always been notoriously fussy but over all it's just better.
Look close at the Broncos.
