Gas engine models of the big three get awful mileage towing (6 mpg for example) and struggle on mountain roads.
Not since maybe the 1999 GM 7.4L did a gas engine use that much fuel towing. I get 8-10mpg speed and wind dependent. 3/4-1-ton diesels get about 12mpg theses days for TTs. And the 3.5L Ecoboost is a mini powerhouse. I have never read of an owner complain about power when towing.
Today's automatics are better for most people for towing. They are designed and built for towing more weight than 3/4-1-ton trucks ever have. I love manuals in many vehicles and believe a good driver has better control with it. But I would not say the average driver is better than modern automatic programming.
For full timing get a diesel. The fuel savings will add up as well as a significantly more pleasant towing experience. Pickups cost less new and used than SUVs with comparable equipment and lower capabilities. Are you open to a full sized van? GM offers a detuned Duramax in them. The 6.0L/6-spd in 2010+ is reliable and strong. They are cheaper than pickups new and much cheaper used.
