That's an interesting TPW between the holidays but great you've made it that far. Been there done that on the wait before but it's all fun and anticipation. This will be one of the 1st 6.2L Trail Boss trucks. Enjoy it!
I test drove a 6.2L GMC today for the 1st time and was blow away with the acceleration compared to my current 5.3. I was already sold but there's no doubt now. Also, the 10 speed is finally going in across the board which is huge as well.
Hopefully I'm not too far behind you with the Trail Boss or an AT4 sometime before then since they already had 6.2 + 10 speed.
