The F-150 EcoBoost trucks come in a number of different flavors. If you have the Max Tow and Max Payload packages, there are people pulling small fivers with those (I know several doing that over on the Grand Design forum). With any 1/2 or 3/4 ton truck, the issue is not what it will PULL, but rather the leftover payload capacity (after the truck is filled up, loaded with hitch and gear and all occupants) and what it will stop. The CAT scales and the GVWR sticker on the door frame are your friends. Do your homework with the numbers - and use the GROSS weights on the RVs - and stay within the limits.
