It's an expensive option that we got on our first MH that worked sketchy at best. Sat needs line of sight, which means tree cover, overpasses etc will kill the signal and it needs to find it again. Most of the places we have camped had trees and frankly in the year we had it were able to use it about 5 times. When you camp you can't move the dome to get a better signal since it's fixed on the MH. Total waste of money IMHO. If I were interested in having Sat TV, I would get a carry out. While you can't use a carry out in motion, you can at least move it around your campsite. But our winegard in motion never worked very well while travelling. More frustrating than anything. If you really want TV while travelling, stream, get dvds, load a tablet and HDMI, all much cheaper and easier options than the $1200 boat anchor we had. Save your money.
And then there is this: My son who is 11, told me, "Dad we are travelling and camping, what do we need TV for?"
