With cruise on, speed is maintained very well, except for the REALLY steep grades.

Towing is all about torque. In the case of the mighty, mighty Northstar 4.6 L V8 limo, there's less torque on hand than the trailer and extra 4 ft in the middle requires, so the 4T80E transmission unlocks the torque converter and downshifts to 3rd, then 2nd as the grade increases. We spent some quality time on the side of an exit ramp allowing the transmission to cool off a bit yesterday.

This rig doesn't strictly love the mountains, but it gets 'er done.
