Thinking of a new TV in the near future. I've always had trucks, and put a cap on first thing. For me the bed is useless without one, firewood, generator, etc needs to be covered, and more secure out ...
The Transit models have a 3500 lb towing limit also. Good choice as long as you don't have a big trailer !
Not sure where you're getting this info - the 2018 Transit guide shows a max of approx 7,000 is properly equipped. The passenger version has lower ratings.
