2003 Avy 2500, I've had it almost 2 yrs. It has just under 140k miles on it. Not sure if the PO did any maintenance to the truck. I'm thinking plugs and wires, trans fluid change (should I have it flushed as well?). Anything else I should look at, diff oil changes, transfer case, etc? I want to ready it for the towing season which brings a few more ?s, it seems to struggle with freeway driving and pulling decent hills. Anything I should look into for helping it perform better in these areas?
