This is pretty much me to a T as well, except the truck is stock. Love the long bed.

If that's the worst thing that happens to your truck I think you'll be ok.

My 21 does the same. If it's a steep enough hill I turn on the trailer mode to make it more aggressive.

I think it'd be 6610+500-1230 = 5880. Somehow you got the right last number, but got the + and - backwards. But you probably have to watch your individual axels as well, as the weight of your configuration could be a lot different than stock.

Definitely not the fanciest truck in this group, but it should serve me well.

Glad you posted this. I heard the noise but wasn't sure what it was. Good to know, and it doesn't really bother me now.

I ordered a Sierra 3500 on December 18th. The dealer called today and said it was sent back by GM as GM can't get something in the preferred package. So I could keep my order and delete the preferred package, or he would change the order to a stock truck and resubmit my build. I told them to resubmit mine as if I'm ordering I want to get what I want, and I'm in no huge hurry for the new truck.
