Thoughts on new Ford trucks with Pro Trailer Backup Assist

They also talk about a "custom set up with the trailer and the truck". So, I'm thinking that each time you hook to a different trailer you will have to take the pickup back to the dealer for reprogramming. That wouldn't work for me very well. I tow 3-4 different trailers during the year and I never know when I might hook up to a different one and go.
