I would just use tow/haul and drive.
I'm not sure what you mean about it not pulling over 55 mph in drive. If it's not going fast enough give it more throttle. That truck should have no problem going over 55 mph with that trailer. The engine will need to spin fast, really fast when going uphill. Don't be afraid of RPMs in the 4,000 to 5,000 range. Let it do it's job.
Some people claim they know better than the automatic when to shift and so prefer the manual mode. Some may shift it just right manually and gain a bit of speed or fuel economy. For most, I suspect the auto. is smarter than they think.
