CSI says that it CAN NOT be open trailered. There is a label on the inside of the door. I put mine on a few months ago and bought an enclosed trailer the next day. They also make your rig several inches taller, as they have fiberglass roof rods similar to those found in compact tents.
Does anyone else have a full soft cab door that looks half way decent? I really liked the CSI door but the other full that is on the market is ugly but may have to do. I'm sure you mean 2013 and up Maverick also?
