Not RVing but my hubby is the type that can't help but rib friends and family and sometimes poor unsuspecting strangers we meet.
On cruise ship and a woman commented about how do they get all the electric to run everything - he said they have a 1000 mile long cable plugged back in at Miami. She actually went "Ohhh and walked away". Another woman different place different time asked him whether these stairs went up or down = well duh!!!
His latest was a poor young fella that was serving me and struggling with his co-workers around him when at an opportune moment hubby shouted out "don't worry, she only got out of jail this morning". The look on all their faces of pure shock was priceless as they believed him and no matter how much I tried to defend myself you could tell they weren't having it.
I've put up with that for almost 35 years - can you believe it?
