From 2016 to 2019 my GMC Canyon (see my sig below) was able to pull my 7K TT up a long 7% grade at 70+ MPH in cruse control. In 2019/2020 GMC remapped the computer so now I pull the 7K TT up a 7% grade at only 60 MPH with cruse control failure. (I need a better fuel map). Most loaded semi's will be doing only 35 MPH on a 7% grade. I still can do 8% grade at 40 MPH (loaded commercial trucks are normally detoured around roads having an 8% grade). The posted speed limit on 8% roads is usually about 35 MPH or less.
Yes, I still recommend a GMC Canyon/Chey Colorado WITH TOW/HAUL enabled for pulling 7K TT on mountain roads. It does a great job (70-80 MPH) pulling on flat roads and has enough weight and wheel base to handle cross winds with a WDH.
