I have a 2019 Cherokee Trailhawk and the death wobble has been addressed for this model year and supposedly has been solved. To date no problems towing this Jeep. I also have my GMC 2500HD equipped for a toad when I want to take my ATV or anything else in the bed. Prior to purchasing our Jeep we had a Honda CRV which is an outstanding vehicle but the newer models can not be towed all 4 down. All this to say that I have found very little difference in towing different vehicles of different weights without much of a difference. It mostly comes down to proper dingy tow set up and the tow capacities of your coach. We recently towed the GMC 2500HD Duramax from British Columbia to Nova Scotia and the fuel consumption did not reveal any noticeable difference from towing lighter vehicles.
