Can it be done safely?

I am a conservative trailer hauler. Have you ever read the assumptions on vehicle trailer capacity. "trailer capacity assumes only driver. Any additional passengers or equipment reduces capacity. So 5000lb capacity, one extra passenger, 4850, gear and so on reducing your capacity. If your intent is to only travel flat land in Wisconsin, probably OK. Traveling west, need to factor 2% capability loss for every 1000FT. I have a traverse with 5000lb capacity and would never consider pulling my 19Ft Jayco with it. When traveling west with my suburban last year traveling 10% grade was getting high temps and slowing down considerably. Without a load leveling hitch I would expect the rear of the travers to be almost on the round. 400lb tonque weight on the rear of a traverse! Traverse 5000 lb capacity is intended for maybe snowmobile trailers, small popups, ... not big hybrid. Sorry not too positive but dealers do not always give the best advice just to sell a trailer.
