Having your wdh properly set up will help the front end bouncing considerably, although realize from the trucks standpoint, it's towing the same size trailer. It just feels better because it effectively move the truck end of the see saw farther forward.
You'll hear that you don't have enough truck for the trailer. Lots of ole codgers here that believe everything they hear and by nature, the older you get, the more paranoid and conservative you get, in general.
For your purposes, were only really talking duty cycle though. Truck is rated for what you're doing. How long it will doo that without significant additional wear and tear is the question.
If you're a weekend warrior and most of the trucks service is daily driver duties, you're good. If your towing that trailer 10-20k miles a year then I'd get a HD if you're expecting max service life out of the drivetrain.
