The range on the wireless bridge is not great but should be able to get through the RV wall and at least 1 wall in the house if you plan to park the RV close by. You could then keep the Genie in the RV and use the wireless mini-Genie in the cabin. With the whole house setup on all receivers you would still be able to watch and record up to 8 channels at the same time and view them on any TV in the RV or in the house. It seems like the Genie plus 2 DVR's is a bit of an overkill but you could eliminate one DVR and add the mini-Genie. You would still be able to watch/record 7 channels. That's just an opinion, not a recommendation.
