Rental truck? which means towing is limited to 5,000 lbs. if in fact it doesn't have any towing options.
You might want to consider adding all the towing options.
535 towing package included:
-7 wire towing harness
-Hitch receiver
-auxiliary auto transmission oil cooler
-radiator upgrade
-electronic trailer sway control
The 60P max tow included the above, plus:
-upgraded rear bumper
-trailer brake controller
Honestly, without the factory towing package, I'm not surprised it warmed up pulling heavy on a grade.
