We have one Hopper with Sling (H2) permanently installed in our motorhome and a second H2 installed at our Adirondack vacation cottage. Both are purchased units though, and we are not under any contract with Dish. On the road, we use a portable tripod mounted dish, and the cottage has a permanently installed dish that's equipped to connect two Hoppers when we're parked there. On the road, we can use the Dish Anywhere app to access either Hopper, and when we're at the cottage, the two Hoppers communicate with each other to share DVR access. When we're away from the cottage, which is most of the time, we change our service location as needed with Dish, which also changes the cottage Hopper, so we lose the sat locals there. The cottage Hopper does get the locals well with an OTA antenna though, so we can still tell it to record network programming that we would otherwise miss while under way. I'd suggest telling Dish you want two Hoppers in your house and then relocating one to your RV yourself. You may have to purchase the second Hopper from Dish or a dealer though, to have it activated on your existing account. There are several online Dish dealer sources with reasonable prices.
