my Tailgater from KING works great, is on a removable mount on my rear roof, and can also handle a second receiver(same satellite of course) - I've not yet moved mine off the roof yet, though I've moved it around the roof for the best signal several times. I did not permanently mount it because I knew that there would be those times when trees might get in the way. I have two 2" by 1/4" studs mounted on the rear of the roof that allows the existing holes on the Tailgater(with a little rounding out) to sit down thru. This keeps the unit from moving while traveling, but allows me to easily lift it off it's mount if needed. I ran my coax cables around my rear a/c(for the extra cable length when I need it), down the ladder, under the coach, and out into the we bay to hook to my receiver cables.
To be clear, though, I also have a manual dish for longer stays, where all three of my main tvs can receive any and all channels. : )
