I stayed at a campground on the Oregon coast and talked to a man with a dented cab and a shattered rear window in his Ram SB truck. His truck was a Platinum edition with air suspension and it was giving him problems as to ride height flexibility. By coincidence, he was towing a new Montana High Country with an AUH hitch. The pin box was biting chunks out of his tail gate, so he reversed something on the hitch. He happily towed the trailer for many thousand miles without issue.
He pulled into a poor access gas station and decided to back out. He was backing tight and the truck went down a driveway dip. The front of the trailer leaned forward and took out his window. The Montana has tapered front corners, but it slopes forward quickly.
The owner was from Minnesota and was very easy going regarding the incident (more so than I would have been). He blamed himself for getting flustered and losing his concentration. He really liked the hitch prior to the incident.
On edit, this was 4 years ago and as I recall, the slope of the front cap looks different than in your picture. Maybe they reacted to an issue. I also believe he had a MorRyde pin box instead of RotoFlex which you will have to lock out.
