We picked up a 2013 Rockwood 2702SS this weekend. The camper is 5,3xx pound dry. Almost 2,000 lbs heavier and 4' longer than the camper I towed with my GMC.
The Ecoboost handled it with ease. There is what seems like an endless amount of power on tap compared to my 5.3 GM. It was very windy when we drove home and the truck did feel light to me. I could feel when a gust of wind hit the side of the camper.
So far we are happy with our purchase. My wife drives the truck 8 miles each way to work every day. She is averaging 18 MPG.
Only dislikes so far are start/stop and the shifts can be a little abrupt until the engine is up to temperature.
