I am not so helpless that I cannot change a stupid flat tire, inside or outside; nor do I want to be helpless because I don't have one! All it takes is a hydraulic jack, a good lug wrench, and some time. It usually takes far less time to deal with it than it is to have to call someone - if they can even be reached - and wait, wait, wait, wait. No thank you. Not being prepared is ridiculous, my daddy raised me better than that. I changed a tire one time about 50 miles west of Stovepipe Wells up in the Panamint range. I doubt there is cell service there even to this day. If the motorhome world has collectively become so millennial-ized that I can't get one with a spare tire, I'll just stay with fifth-wheels.
I had a flat tire on my car a couple of years ago. Without getting into the gory details, when it first happened, I wasn't sure if I'd lost a half shaft or just had a flat. I just happened to be forced to stop right by some highway workers. They told me that they "weren't allowed to assist me" - that was fine as I hadn't asked them to! While I was investigating the issue, they were wasting my time asking stupid questions: "What are you going to do?". "What am I going to do? I'm going to crawl halfway under this car and check the half shaft. When that's OK, I'll change the tire and be on my way." They were flabberghasted - I guess they were used to wimp Americans that seem to be the norm these days. Jeez, I have a nephew who can't even drive a stick shift.
