Going downhill the one tap of the brake downshift is, IMO, essential to safe operation and longevity of the brakes. Using the engine as a brake will keep you from riding the brakes and thereby overheating them on moderate to steep declines.
On flat land depending on the speed limit of the road being traveled I may or may not use tow/haul. At lower speed limits tow/haul may cause the trans to ride at the lower end of one and higher end of a shift point thereby causing numerous unnecessary shifts between gears. This is more common off interstate than on interstate. Within a city I generally turn tow/haul off if I am not towing.

Good explanation of using the T/H mode on the V-10 in a MH. The only time I may activate mine in city driving is if there is a ton of congestion and I desire more engine braking.
