I just joined, although I don't own an AT4. Yet. I'll be purchasing a 2500 or 3500 AT4 HD Duramax in Pacific Blue in the coming months. I've test driven a 2500 already. However I decided to refinance the house first, and I assume that one will be sold by the time the refi is done, so I may have to order. If I do have to order, I'll be ordering a 3500. I have a 33' travel trailer, and my 2011 Sierra 2500HD SLT gas struggles with one particular hill when pulling it to the peninsula. If that's not a reason to upgrade to a Duramax, I don't know what is...
