I'm brand new to the forum. My issue is with length of bed. I was treated very kindly by a guy who lives not far from my house. He sold me his F250 with an 8' bed and a Jayco J pop up camper on it ...
I don’t think you’ll have any issues with a short be on a newer pickup, but if you are talking about old pickups, it would be good to have more information.
What year range pickup with what options have you looked at? Have you looked at CarGuru, Autotrader, and Ebay?
