*UPDATE*Calling Duramax owners 1st trip with camper bad fuel mileage

Sorry I havent been back for a while.
I had a couple of bad weeks about the time this thread was going on and my home and camper got destroyed by hail shortly there after, so
I didnt feel like doing the forum thing.
Never made any progress on my truck. I cleaned my MAF sensor and plan on deleteing the egr and getting efi live programming as money permits.
I'll also get some Michelin lrr highway tires and with those three things i should be able to get better fuel economy.
