I don't know why they don't offer it to rv'ers. I took my household hopper with me when I hit the road last year and have had zero issues. I have the hopper w/ sling which is, I guess, a little different than the current hopper 3. I don't know if they are THAT different though. Like I said I have a hopper w/ sling, I also have a wireless joey for the bedroom. I use it with an upside down 1000.2 dish and only have the usual troubles aiming it.
