I know NOTHING about newer Jeeps, mine is 44 years old. I thought Cherokees were known for good mileage. I would much rather have him a full size pickup... Hmmm... we may be looking at the Chevys againWell you just threw up a big contradiction there. 4.0 Jeep, and an Automatic is going to get no better if not worse than a mild fullsize truck. Not to mention most people want a premium for a YJ/TJ and you could be in a fullsize truck for 1/2 the price. When I was DDing my 97 TJ with the 4.0 and 5 speed I was averaging only about 15mpg with about 17-18 hwy, an auto would be a couple MPG worse. My 88 Chevrolet 1500 4x4 with the 350 TBI and auto would do the same average around town, but would get up as high as 20 highway. Both vehicles were on the same size 32" tires, and both had 3.73 gears.
Of course the Jeep would be more offroad capable out of the box, but fuel mileage is not the reason to rule out the truck, especially when you consider the initial cost of the Heep is higher than the truck. An XJ on the other hand can be had for much cheaper, but will still get the same if not worse fuel economy.
And like I've always said, if I'm going to be in a wreck, I want to win!
