I know: Even my 02 was a better engine than the 05. The new style trucks drive nice though. I often thought about swapping a 12V into a newer body. Mines okay for mileage (not great) empty but it's no heck loaded.
The kid is selling his 93, 5 speed dually, I told him it won't be an easy truck to replace as it's got all the right stuff. I think he should paint it and call it good myself, maybe put some softride front springs in it.
