Hello,
I would recommend making sure you buy one with the air suspension. If you go to the "suspension" forums on this website and read some of that stuff you will gain a ton of knowledge. Your camper seems like a light one, so you might not have issues, but for peace of mind, I would go with the air suspension. I am stock and it sucks. The ecoboost motor is MORE than capable of towing the load, but the independent rear suspension is not the best set up for towing. And believe me when I say there is ABOSULTELY NOTHING out there aftermarket to help make it better. NOTHING.
It has been recommended to me to buy a weight distribution hitch made by Equalizer. Apparently they are the best on the market. (and the price reflects it) But some kind of weight distribution hitch is a must.
