Just checked tires and inside tire is flat. This means that I will get ext today. Bummer
You found why we're so passionate about having good valves and good access for checking and airing up.
Actually, you're very fortunate that you got into this discussion and finding the flat this way.
Any flat is vexing. An RV blowout can be disastrous. That steel belt flailing around can cause thousands in damage, cripple the RV, create fire risks (broken LPG lines) and more.
We had braided extenders on our first Class C, connected to steel valve stems. We didn't have actual problems, but added air more often than we do now. (Now, BTW, is about twice a year!) Some braided extenders are "airless." They have a core that doesn't open the core of the actual tire valve till you press a gauge or air chuck onto it. That isn't a bad approach, but one-piece valves are still the best.
You can do it on the Cheap. Steel valves with air through caps. Carry your own "truck" air gauge and air chuck (the "straight" style) or depend on those who have them. For me, it's RVing, supposed to be easy and fun. I wanted a setup that anyone, anywhere, anytime, anyplace could service our tires.
I, by the way, was a holdout. We have the Ford wheels with eight small "hand holes" and Dicor stainless simulators over them. It took me half an hour to check tires, and it called for one or two more hands than GOD gave me. I was sick and tired of getting dirty and angry doing a simple task. Now, I can use any gauge, any hose, and in minutes I confirm they don't need air again.
