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?

With my 2005 Duramax/Allison, if I am hitched up to our 12K 5th wheel, I put it in T/H mode and forget about it; flats, uphills, downhills, and have had no complaints/issues. I even sometimes use it when not towing if on steep mountain roads, it keeps the tranny from hunting needlessly between hills and flat areas and saves braking; has been great for that too.
