I purchased a 2019 Atlas with the factory tow package with the intention of towing a travel trailer. Looking at the weight ratings, I purchased a Coleman LT17B. It weighs in at 3,000 lbs dry and has a tongue weight just under 500 lbs. I took my trailer camping around a dozen times the year I purchased it as well as taking it on a 500 mile trip. I used the standard hitch that came with my Atlas. The only modification I made was adding an electronic brake controller and I used a hitch tightener. I never had an issues with sway or porpoising. I was concerned about sway, especially in Oklahoma winds, but never had that issue. The trailer does squat the rear of the Atlas somewhat, but there were no issues with the suspension nor any safety issues while towing. The Atlas was able to tow my trailer with no problems or issues.
