I would like to hear from any RVer that uses one on the road.

I havent seen any,however was considering give it a try someday,
The big question obviously is where to mount it..
Maybe lay it horizontaly on the roof and raise it when parked boondocking..
Or mounted on the back bumper and raise that up higher when stopped..
