One problem with the ZJ is the auto climate controls and associated
stuff...if that ever goes out, the labor costs are horrid. Some folks
never have trouble, some do.

The ZJ is more aero than the YJ, but kinda like comparing s sloped brick
to a brick. I've never gotten as bad as 12 mpg unless I am offroad in
lower range for long. Around town with fairly moderate hotrodding I get
in the 14 range. This is on streets and mixed expressways where you can
run it up to 45-50 and get the torque converter locked up nicely. For
freeway cruising at speeds from 65-80, I get about 20-22 depending on
gas brand, heat, and time of year [lower in winter]. Only non-factory
mod is a cat back.

Except as the speed goes up the better body shape of the ZJ helps. A
bit. The ZJ is pretty light as well.

Depends on what you plan to do with it.
You can get the part time 4 wheel drive which is arguably better for
mileage and still available when you need it. This one has 2 hi, 4 hi,
4lo positions. Or you can get the full time which has only 4 high and 4
low. I get the 14-22 mpg with the full time.
The ZJ can be turned into a good dual use machine, put some Edelbrock or
Ranch adjustables on it and you have a fairly decent highway machine
that still can go offroad to a good portion of the trails that the more
capable wranglers can go--and get back to the road at the end.

On my '93 ZJ the bezel doesn't mention the name of the t-case. However, the
sun visor does. ;)

The part time on the 231 should behave exactly like the part time on the
242. It may be slightly beefier but the performance should be identical.

FWIW, I've beaten the daylights out of my Quadratrack (249) and found
it quite capable on loose dirt and switchbacks. Lack of proper ground
clearance (and skid plates) keeps me off the rocky bits. Later models
(I think) have a low range lock. Mine is limited slip in both high
and low.

'96 and up 249s lock up in 4 low.
They'd be a good transfer case if it wasn't for the viscous coupler. When
they go out it's an expensive repair.
