If you search for them you will find numerous posts of good and bad.
We have been members since 2006 or so and I am happy for what they are. For the time we camp and the cost of the membership and dues we get are monies worth out of them as far as I am concerned.
When we first joined they were pretty much exclusive to members. Now they seem to let anyone in to camp, so not much different than a regular campground in that regard. But, with that said I have never had a bad experience with any campground in the TT network or other campground (except one in OC, MD). They now also have a ton more cabins and a few I have been now have many seasonal sites that take up a lot of the spots.
I have read many people complain of their quality and friendliness of the campgrounds. I must be very understanding or something but I have not ever experienced this issue. They have only ever been very helpful and understanding. Even had them offer to let me borrow a vehicle when I had a brake issue in NY state. I have camped there in a pop-up and now a trailer. Never was treated poorly.
Would I buy into TT again? If they were the same as they were when we joined, yes. We are members for life, low dues, access to TT, OW, RPI, NACO, Encore... Blah blah. We have nationwide coverage and can pass along three times to family, no zones or expirations. With today's rules and reg? NO, now It sounds like it is 2x the price higher dues and only good for 10 or so years I think. With what we have now it made sense for the camping we did. Now I would have to really look hard at the cost v staying at any other private CG when going away to see if it would be worth the $7,000 buy in and $800 dues.
