An 03+ would have a 4 speed auto with OD. Any 5 speed TJ, or any auto or 5 speed XJ would also have an OD tranny.
We've had three Cherokees. The pair of 2001 2WD's always weighed more than 3,400-lbs (full fuel, no driver) when on a certified scale. The 4WD's can easily get above 4,000-lbs with driver, fuel, tools and some aftermarket. They also have an OD automatic. You won't know what yours weighs until you put it on a scale with yourself, business tools and supplies plus full fuel. That's the minimum weight, IMO.

Delivery service is hard duty, no question.

FE is important but it fits into an overall picture. What is the average speed over a work day (engine hourmeter divided into total miles)? That's where the problem lays. Thus an understanding of all costs is relevant, as that Jeep has short maintenance intervals. Brake adjustment (two weeks or less with rear drums), alignment, etc all need careful attention.

Cost projection over an estimated lifetime is where to begin:

My truck may achieve .14 cpm in fuel cost, but my overall is .56 (and I need to update it, that's a bit high for calendar 2010).

FE is relative for a business vehicle. "Icing on the cake" at best, assuming the vehicle is well-chosen for it's intended purpose.
