I leave it in tow/haul in my 2011 3500. It does every once in a while downshift a little aggressively, but you can just feather the gas a tiny bit and it won't downshift. Or use the cruise if it is a straight road with no traffic.

I do the same with mine

Same here too.

Yep. Tow/Haul with automatic exhaust brake holds speed very close.

Tow Haul auto for me.
I set the down hill speed and the tranny holds it there. RPM's go up but that's the way it works.

Great featured.. never touch the brakes going down a hill unless I want tow haul to reset to the new slower speed.

I usually turn TH off on downhills, preferring to select the gear I want. Same on uphills.

I engage tow mode, exhaust brake, and cruise control and never touch any peddles on the floor. Mine holds steady within 2-3 mph difference. It shifts down and up on it's own to hold the speed, and is absolutely marvelous with towing the trailer up and down mountains. I think the steepest grade I was on was 5% (Appalachian Mountains in WV). I let it down-shift, and never gave it a second thought, even when I though the RPM's were a bit high.
