Tow Haul.......When?
2003 GMC 2500HD pulling a roughly 11,000 LB 5th. Would you leave it in Tow/Haul on flat/level highways? Or do you put it in t/h and leave it?

I rarely use T/H. The majority of the time it keeps my truck in a gear (or two) lower than needed. I'll use it on a big downhill grade,but switch it off afterward.
