Dang that is aggravating Hugh.
And yours is a nice big ass motorhome. ��
The only time I've been stopped by tire trouble in my coach was the day after having the wheels taken off for balancing. They left the stem extender on an inner dualy loose causing the slow leak.
In checking around I found that they had not torqued a number of the lug nuts either.

I pumped it with the compressor and limped for hours back to the shop for them to fix the leak, this time they left off a couple of valve caps.

In the few years I've been involved in RVs this lack of quality work seems common from the stories I've been hearing.
Glad you can get you issue fixed so reasonably. I'd bet your lug nuts are not torqued
Correctly either.
This pattern keeps me motivated to do as much myself as I can.

Now that I've removed most of the wheels for brake work, and for access thru the wheel wells to the side of the engine for exhaust header work. The thought of dealing with a flat is a lot more comfortable.

Cheers Richard
