We have the same gen, being an 05. Bought new, 5.7, 4x4, all the bells and whistles. Has just under 110k on it and other than routine maintenance and a water pump earlier this year it has been trouble free. Cant speak for others but ours is 100% rust free, but we're quite anal about washing, waxing, etc and for most of its life it's been garaged. Lots of room, have done a lot of travel with the youngster in it, and it's a capable off roader. Good luck with whatever you decide!
