Yes, you can easily and inexpensively change the SK-3003 (DirecTV SDTV only) to Dish. You need a new dish, arm and LNB and you will need to do a bit of reprogramming of the controller inside the coach.
I believe the replacement Dish/arm/LNB combo costs $200-$300 and you should be able to do the conversion yourself if you have some tools and don't mind going up on the roof. The 2 parts packages you will need are:
RPSK – 11 Dish reflector
RPSK – 21 Misc. hardware
You can call Winegard customer service to order get the exact pricing.
