I have towed with a 3500 for over 20 years. Current camper is 39 ft. from ball to bumper and around 11,000 lbs. I have the 6.0 engine.
I almost always use the M setting when towing, normally M-5 and tow/haul button engaged. Tow/haul changes your shift points for towing. When using M I use the RPM view and keep it around 2200 on fairly flat ground, through the mountains and hills I use whatever gear keeps it in the mid 3,000,s. At times it will be in the 4000,s to keep up speed.
With the using the M and not in really large hills I am able to use the cruise set at 62.
Read your owners manual under towing.
Using just the D setting and you are not on flat ground and no wind causes the transmission shifts A LOT, especially in and out of overdrive. That causes the transmission to heat up more and shortens its life.
