Could the difference be just a matter of semantics? I know Dish, and at least some dealers, will not do or support a Hopper RV installation, but I had no problem getting a self installed purchased Hopper and Joey activated on my existing 211k account for my coach via a DIRT representative. So it seems that while they do not support the installation and will not supply the equipment free with a contract, they don't object to activating subscriber owned equipment installed in RV's on a month to month account.
