I have a 98 Chevy 4x4 extended cab 6.5 ft box with the 5.7L vortec and factory trailer tow set up with electric brakes for trailer that I use for parts runs and towing. It has only 86 k on it now. I put a Kenwood Excelon bluetooth radio in it with a subwoofer so I can jam on long road trips and not think about the mileage...
Mom is using the GC right now. It used to be dad's. I get it when mom is done with it. It is the only year that they put the 5.9 L in the Grand Cherokee and it only has like 42 k on it right now.
