i was just looking at the facebook pics of that red reg cab chevy, was that a LML? I thought the hoods were different than the LMM's, it looked the same.
I loaded that tow tune Ferm and so far so good, I ran empty up to Laramie Wyoming from Fort Collins yesterday and there are some pretty steep hills and the truck climbed awesome, had plenty of power and shifted smoothly. I will let you know how she performs with 10,000lbs behind her!

thanks again!
