Just want to put it out there for you...
Our SK-1000 will work with any DISH receiver. DISH does not support RV's, but that's what we are here for. You have a Winegard satellite antenna, and we will definitely support you with any problems you incur with it. The SK-1000 is pretty much the same exact satellite antenna that would be installed at a residence, just on an automatic auto-seeking turret. If you ever run into any problems with this unit, feel free to email me, or call our technical support team at 800-788-4417. Hope this helps!
