The older Cherokee's were often used as Mail delivery trucks, and that is similar use. But didn't see the WJ's used by Mail carriers, maybe because they were more expensive line of trucks when new.

Ram is worth about $8600 retail now. So I'd be spending $2000 on the WJ to keep the truck clean and low mileage, and avoid a truck payment in the future. But I'd have another vehicle to maintain and pay insurance on also.
