Do you use the tow/haul just going down the grades?

You can use it all the time. It will hold lower gears going up hills, and also downshift for slowing traffic while in town. The only time I found it to be a hinderance is cruising on flat highway. In that situation, turning tow/haul off may be desirable because it will stay in Overdrive most of the time, vs tow-haul where it shifts a lot to maintain max power.

Pretty much comes down to personal preference.
