I can tell you one campground that Thor's cheap tv's do not work at and that is Ocean Lakes Campground in Myrtle Beach, SC. We learned the hard way and had to replace all 3 of our tv's with Vizio from Walmart while on vacation. I called Thor and complained and it did no good. They said they were unaware of any problem with the Seiki tv's. Make sure when you replace them, the new ones have a QAM tuner!!! Ocean Lakes is the only one that we have experienced the tv problem with. We visited Anchor Down Campground and the ole cheap tv's worked fine. I just purchased a new motorhome and the first thing I asked was about the tv's.
