Winegard Carryout G2+ Satellite Dish

I have used a G2 for several years and really liked it but sold it along with my fifth wheel. I have now bought a new Class C MH that is not equipped with an outside Sat. hookup so I am having to do some modifying in order to have Sat, cable and O/A available. Bill.Satellite has given me instructions how to accomplish this but do not know if the G2+ with power power inserter will work with the way I will be hooking things up. Just dont know whether to purchase the new model or not. Sure sounds good.
