I had a person on here send me a private message to tell me that I did not know how to pronounce the area I live in. He said that he had lived in western Tennessee at one time and that is not how it was pronounced. (FYI - the Appalachian Mountains do not run into western Tennessee)
He sent me 2 or 3 PMs and I finally blocked him!!!
There are those people that just try to get something started. You talked about towing and tech related. Ask something about carrying a gun in your RV. That will sure get them rolling!!:E
There will be some of "those" people out in the parks, but usually, they stand behind the anonymity of the net.
If you do have trouble backing in, just look around. There will probably be one or two watching you, that would be glad to help if you just ask or indicate that you are open to it.
