Remember its stopping power too here.

Goose-neck or a tow behind, makes a big difference in how a truck drives/handles.

I haul equiptment all the time on a 00 and 01, 3500 cummins with tandem gooseneck. Great trucks, like pple are saying its a great motor pulls the same empty as loaded. Greatest investment is the Jake brake option when your hauling 30,000 lbs flying down the road. Does GMC or Ford offer this, anyone?

Transmission is a little finicky especially reverse. Just replaced the clutch at 180k on one, the other does lighter hauling and feels like new.

Biggest thing is the steering issue on these models but other than oil and filter changes, one rear end seal, and the damn easy to break parking brake releasers nothing comes to mind.

But it all depends what you will realistically do with it.

Happy buying.
