03 Silverado 2500HD LT 4x4 Duramax 6.6 / Allison

Getting ready for the 7500 mile service from the dealership, What services should I be making sure are being done, and what does anyone recommend I get done. We haven't towed a lot with this truck yet, but are planning a lot of weekend trips for 04.... Thanks!!!

Just the norms. Obviously oil and filter, lube all parts. and I always change out all fluids at the first service. Only because of the break in process. Trans/transfer/differential. It might be overkill, but I always go the extra step. Go ahead and hit the fuel filter while your there.
