Aside from the FWC Project M there is very little wedge or pop up style camper for the 11th gen F150 in the market. Go Fast Camper could provide an option if they receive enough requests. For anyone interested in this here is the link to their newly launched "request" form. If there is enough interest they will add this body style to their next production run.
