How do we know if TPMS system is installed?
I went to check the tire pressure on my recently purchased Class C. The rear duel tires did not have a stem to allow me to use a tire gage. I then wondered if I had the TPMS system on my tires. ...

Generally you'd have a receiver module somewhere near the driver's seat if you had an aftermarket TPMS system. My guess is that you don't have one. Most of the ones I'm aware of used on motorhomes have sensors/senders that are also valve stem caps, but there are other styles of senders available too, at least for some vehicles and applications. (Some replace the valve stems entirely, others just sit inside the tire/wheel and aren't externally visible at all.)
It sounds like you need a dual head air gauge (and air chuck for filling). These are not hard to find, and have a sort of angled bit at the tire valve end where one part connects more or less straight forward to access the inner valve stem, and the other part points backwards at an angle to get at the outer wheel's valve stem.
There are a couple general styles of these available, the more common ones with the two connections in line with each other (and so both angled), and then a style where the one for the inner is not angled but inline with the body of the chuck or gauge. The latter I find more convenient for the wheels on my motorhome, though either one can be used.
A lot of people like metal extended valve stems which make access a good bit easier.
Edit: Just to make sure it's clear, the valve stems for duallies are generally in between the two tires--that is, the stem on the outer wheel points inward, and that on the inner wheel points outward, and both are accessed through the hand holes on the wheels. It's somewhat of a pain, frankly.
