Mileage are approximates: Alternator 105,000mi, water pump and starter 120,000mi, radiator 95,000mi, A seal on the transfer case where the drive line hooks up 80,000mi, and a new set of front break calipers a few months ago. Everything else works perfect.
I have put a 6 inch lift and 35 inch mud tires on this truck, warn winch, and abused it for years in the hills buried it in snow / mud up to the doors with no troubles, but no its not all dented up, I keep it washed and waxed. I have had this for over 7 years and never had to do any major work to it. I had drove this truck hard from time to time (I'm a lead foot) plus Ive hauled heavy loads of wood, towed boats, trailers, you name it. I was surprised with the power of this 305, I can smoke my 35's (done it once to see if I could). Doesn't burn oil, all the power stuff and A/C still works great, nothing leaks. I have heard of the auto transmission trouble, but the only thing so far is that it slips just a little going from 1st to 2nd gear, but only when I accelerate hard. I think this is a great truck and someday I hope to buy a Chevy Duramax.
Hey, loved the review, I own a Chevy too. Mine is just a simple 97 Chevy 1500 ex cab. Hope yours stays running strong.
