I use the Pathway 2, I think it is called. And the 211z inside. It is self aiming and is powered thru the coax. I calculated the cable length inside the trailer. And in my case it is over 30 feet long and who knows how many adapters/connectors. So I put a direct wall plate thru the wall right behind the tv. I am able to use a 50 ft RG6 cable and can move my dish around. Oh, the reason I went with Pathway 2 is it has a quite a bit larger dish which works better thru clouds and rain, etc.
I do have to get it pretty level and find close to true north for it to lock in tho. And I have 2 cell phones with a compass and the each think north is about 15-20 degrees apart!! So finding north is sometimes (often) problematic.
