Also I have found that RV park cable TV is not always reliable. Many times the parks we have been to have marginal cable (weak signal) or no signal at all. While no cable at two parks would seem to rule that out, it is still possible.
Of course, it is equally possible that there is a sheet metal screw sticking through the cable, courtesy of Thor.

While you might tend to want to have the dealer check it out, you can at least ascertain the problem easily without the hassle of taking it to the dealer and having it sit for a month.
