Well, not sure about the expert part. I'm getting confidence on backing/turning, but you know how that goes. There's some beginner's luck and that can get you in trouble so I'm far from feeling cocky.
Glad to hear it wasn't just me finding that these campground owners... er, uh, "stretch the truth" rather liberally. I don't like making a reservation for a particular campsite though, and then arriving to be told magnanimously "we gave you an upgrade to one with sewer connection and we aren't charging you for it." Only to find that yes, it does have the sewer so I don't have to step on the brake on my way out of the park (big deal) at a dump area, but that said claimed "upgrade" means getting squeezed into a site that shouldn't even be a site in the first place. As for your satellite situation, that lie would annoy me even more. I think they gotcha. You've driven to a place you've reserved (usually with no refund if you don't take it) and you're on your way through, staying for only one night, probably tired and not into shopping elsewhere. But this is THREE campgrounds out four where they painted a picture that was not the case. I'm going to be much more specific in the future and make them confirm their answers with some detail because at that point you can book elsewhere.
What I did find interesting at one campground was the psychological game obviously found to work as it was used the same by both the mother (my first time there) and her son (2nd time) was that if you find something wrong --compared to what you had reserved-- they both had the trick of trying to intimidate you by acting as though you're being unduly picky. She got me on that one the first time, but when he then did the same thing also on my 2nd visit, I stood straighter and said, "yes, that's what I mean," and looked him just as straight in the eye as he'd used, expecting an answer. And he backed off (a la "ooops, she ain't buyin' this"). I just found it annoying that they both seemed to have a ready shtick for when people arrive and aren't given what they were agreed to be given.
I LOVED the trip though. And yes, fellow campers were VERY helpful. And interesting! I had very nice neighbors every time.
Speaking of satellite -- a fellow camper was telling me he had just a regular housetop dish that he would just put in a sunny clear place, and he'd get Dish Network off of it. Is that how yours is, or is yours mounted on your motorhome? This sounded like a pretty good idea. Beats what they call "cable TV." Some of this "cable TV" seemed to have such basic channels only that I'm not sure if it matters over an antenna.
