Joe, there is a lot to learn about satellite reception. My suggestion to you is please take your time, There is many past threads on this subject that probably got worn out. So do some searching.
From what I learned, I will just give you a few tips. The Winegard Travler appears to be the best fixed mounted. Dome antennas suffer from rain. Fixed mounts may have tree problems and is why some even have a mobile antenna as well. Local channels are only available within a spot beam of your home and you generally do not get locals in your camping area. An exception to this is if you sign up for an RV account with Dish,
DISHForMyRV: DISH Mobile Satellite Systems & Pay As You Go TV for RV, Camping, Tailgating, & the Great Outdoors
With this account you have a billing and service address. You can call them and change your service address when you are on the go and thereby get locals This account also has not contracts or fees and you pay as you go. Dish doesn't advertise but they have a starter package that is like $29/ mo.
Take your time on this upgrade because it could bite you later for a wrong decision.
