Isn't it ridiculous, though? And I've been RVing for 22 years and no one in the RV industry has been willing to think outside the box and come up with RV rear wheels that have dual rim inner valve stems easily accessible.
And the rims, even on the bigger wheels don't have holes big enough for you to get your hands through. And, despite all the bad publicity about the problem, they are still making them that way.
And it's not just filling and measuring the inner tire air pressure that is difficult. You also want to use tire pressure monitoring devices on the stems and you can't get in there to install them or to change the batteries.
So, everybody uses valve extenders which, though, many shops don't want the liability of installing them, the extenders are reliable. You can use either wire mesh flex hoses or, if you can bend your inner brass valve stems to line up directly with the holes in the rims, you can use solid, straight stainless valve extenders.
But remember to always use rubber gromets in the rim holes for the extenders to pass through. The gromets dampen the vibrations of the extenders so they don't fret against the metal edges of the holes.
I've used both for over twenty years and the only problem I ever had was when I didn't bend the inner wheel valve stem so it lined up exactly with the rim hole and the straight extender did not seat completely causing slow leakage.
