Tips on using Tow/Haul mode for engine braking
We'll soon be doing some driving through some North Carolina mountains and I'd like to brush up on tips for using the engine breaking feature in tow/haul mode.
I realize it depends on the downgrade, but generally speaking does simply engaging the tow/haul mode provide sufficient engine breaking on most grades or do you find it's necessary to shift to 3rd, or even 2nd, with the tow/haul engaged, to get adequate engine braking?
Appreciate any thoughts.
