I just put the traveler on my 07 Fleetwood. I used the direct tv genie. In my setup each tv has a receiver. So I have a main box and two minis. I had to run coax to the back tv and a coax to the outside tv in order for the system to work (from the SWM connecter in the av cabinet). I could have used wireless but I thought this would be simpler.
I am not sure from your explanation if you are trying to use a splitter for the tv. You will need a box for each receiver.
