I considered the Ecoboost F-150 a couple years ago but decided on a Duramax. I knew a new camper was in the works even though we were not sure which one. The reason I went with the Duramax was the fact it is better having too much power and not needing it, than needing more power and not having it. We ended getting a new Eagle TT 284BHS. Loaded it's over 8K, too much for any half ton truck.
One fact I'd like to point out. When it comes to 5th wheel trailers that are "half ton towable", it is always the camper manufacturer that makes the claim and not the company that made the truck. Just sayin'.
