Some people understand "different jokes for different folks." Others may think their choices are better and superior to others, but I think they are a small minority. As I've gotten older, I really don't care what others think, especially about my choice of RV and I try to avoid judging others and compensate for the biases that I do have.
I can only remember one occasion where we were snubbed due to our RV status. We were having a conversation with a fellow camper, and it came up that he had a DP. When he learned that we were in a pop-up, he couldn't end the conversation fast enough. Otherwise, we have met a lot of great people that were camping in all styles of RVs. I'm happy to see other folks camping in whatever style they choose and can afford.
