If you went with a 2wd 5spd and kept the loads light, you'd see some good results from the '91+ MPFI 2.5L engine. But with a few friends and camping gear that 4banger will be struggling and the end results would be similar to that of the 4.0L engine that doesn't have to work as hard to do the same thing.
I've got a 4banger and love it, lots of power mods, fun to drive, and good mileage. But for your intended use I don't think there will be much to gain.
