I don't think the rating of the truck has anything to do with it. The placement of the car is going to have a direct affect on the tongue weight, which will have an impact on weight on the rear suspension of the truck regardless of the truck's rating. When we got our enclosed a few years ago we were very careful with setting up the full load tongue weight. I could roll the car an inch forward or back and completely change the weight on the tongue scale. What it came down to was loading each car in and finding the perfect vehicle position over the axles, and then marking the position of each car. I know it was said that everything was done correct and by the books, but we are all human. Maybe the car actually wasn't correctly loaded over the axles prior to leaving.. There are so many variables to this, we'll probably never know the answer.
