I have a 2018 Bighorn 3160 El and currently we are using a playmaker dual for dish network. When I try to connect it to the coax connection in the side box, it is flaky at best. Usually have to go through the connection process many times before it will find all of the satellites and sync up if it ever does. More times than not I have to run a coax in a window and plug it straight to the receiver which is not the way it should be. The camper is pre wired for a trav’ler and I am considering going that route. Has anyone else done this? If so what were the results? I don’t mind spending the money on it if it works but would be pretty upset spending close to 2k on something that has the same issues.
