We use a King Tailgater and Dish TV. The monthly cost is an extra $7 on our regular Dish bill and they will put that on hold anytime we store the RV and I call them. The equipment cost is about $400. We have had it for a year now and it has been trouble free. Finds signal within 5 minutes of starting the setup. At first I used the unit as a portable thinking I could more easily find a clear signal spot to dodge trees but in the end fastened it to the roof as I found it was a wash as to whether being able to move it around beat the advantage of the extra 12' of elevation provided by the roof (found when it was 'loose', I was frequently climbing up to put it there anyway). You just get in the habit of requesting a site without trees. Sometimes, in really wooded areas, you just have to accept the fact that you will be watching DVD that night. There's a small campground off I-80 in CA at Dutch Flat that is nothing but towering pines except for the road through and the spot to park. You have to be a magician to watch sat tv there! If you do mount one on the roof, be sure to put it at the front of the coach. Unless you unplug the receiver, even when turned off it will often make a whirring noise as the dish occasionally readjusts to satellite signal variations. We learned this before I permanently mounted it and would climb the rear ladder and set it on the roof over the bed! You ALMOST get to sleep and "WHIRRRR"! The Tailgater has outputs for 2 sat boxes so can only service 2 tvs (that means an extra $100 receiver and another 7 a month). With tv inputs being HDMI now it's a little trickier sending the same signal to multiple TVs. You can do it with the old coax but your picture is probably not going to meet your standards of comfortable viewing now that we are all spoiled by HDTV. We use a single sat box for just the main tv. Our 2015 Winnebago has 2 'network' cables from the entertainment bay to the main TV and came with a network to HDMI adapter at each end (see link). That was my first time seeing these things. They do work very well. Getting the right type of cable pulled to the proper place on an RV can be a real trick. The outside TV is the 'dvd movie tv', and though the bedroom tv doesn't get used often, we'll watch antenna or park cable on it.
