Just bought my first toy hauler

I have the Dish tailgater, it is super slick. If you don't use it for a period of time you have to call and get it "zapped" with the authorization signal for it to work. Something to think about if you're boondocking where there's no cell signal. Also must have a clear view of southern sky so trees can be an issue as with any satellite. I bought the receiver at Camping World for about 100.00 on sale, watch as they come up frequently along with the antenna. I got lucky and found a used antenna for 200.00. We just used it to watch Anaheim 1 out in the desert via projector and screen, it was great sitting around the campfire watching SX. As for T.V. size I'd get as large as you can fit where you want to put it. Sounds like you're on the right track, have fun with the kids' racing, nothing better in my book than passing on the passion of dirtbikes to the next generation (I'm working on my grandson now!).

And WELCOME to the nut house!
