We use standardized 2" powdercoated metal tubing for our dummy hitch. There is going to be some play or wiggle between our dummy hitch and a standardized receiver on a vehicle. If there were no play it would be extremely hard to get a hitch in and out of your receiver. Because FanPole is not the only product that deals with this issue there are some solutions out there.
We are working on a 2 flag system. There are some unique challenges with this system. The drag from 2 flags is significantly more than just 1 flag. We hope to have a production 2 flag system by the beginning of 2017.
