| The only thing i would check out would be to see if the injectors had been replaced. The LB7s that came in the 01-04s had some injector problems but were fixed with the new ones that they replaced them with. GM upped the warranty on them to 7yrs 200000 miles, but a 01 would be out or close to being out of the 7 yrs. The service dept at the dealer should be able to pull the service history on it. Other than that they are great trucks.
