Again, the dome "should" work with DirecTV but the issue is no HD programming and will not work without the SWM8 hardware if the OP plans to use the equipment DTV installs in his homw. I am not sure that the Tracvision dome is even capable of using the SWM8 kit.
The dome "should NOT" work with DISH and WILL NOT work with the Hopper/Joey combination that would be installed in his home. A new portable like the Pathway X2 and a separate Wally receiver for the house or left in the RV would work but require some coax cabling updates.
