If you opt for the tire pressure monitoring system check out HawksHead at
http://www.tpms.ca/
I installed it on our PW and love it. Made in Canada and a little bit less expensive than the competition. Wish I had had it when we were towing a big 5th wheel.

I notice that the system uses senders that screw on to the valve stems, instead of the inside the tire type. It reminds me of the old pop-up Tire-minders, which seemed to have recurring problems with leakage. The sensor has to open the tire valve, or it wouldn't work, so any sealing issue, either to the threaded stem, or internally, would flatten your tire. You would also need to remove the senders to add or subtract air from your tires, which we do pretty often to adjust for ambient temp changes. Don't know if that is an issue with that style (I will be checking it out), but we may wait until we need new tires and get the inside the tire type, which wouldn't have that kind of issue.
No doubt that having a tpms system is a very good idea.

I have the HawksHead, and don't have a problem with the senders leaking. The few complaints that I do have are that the senders are not very accurate. They are anywhere in the neighborhood of 5 psi off. The second problem is that occasionally the Sandor will not register after stopping for a long time. To fix this I just unscrew the Sandor and screw it back in and it seems to fix the problem. Besides that, so far so good. Have had it for 6 months or so.

Nitrogen "air" is fine. Pure nitro is a waste of money.

I went to a lecture at a large RV dealer which was selling both moniters and nitrogen. One of the arguements was that oxygen would leak out of the tire faster than the nitrogen...bad arguement. If that were true--then we would all have pure nitrogen in our tires as oxygen leaked out!
Airplanes which go to 30,000 feet, and the moisture in the tire would freeze and cause ice. Reason for pure nitrogen. Race cars, where the tires would run cooler--good reason for nitrogen..but that is it...

Here is what I can tell you from personal experience with both air and nitrogen in the same tires on the same coach. We drive our Roadtrek to Florida from the Midwest each July. One of the days we typically go 10 - 12 hours in a day through Tennessee and Georgia. It is typically very hot and if you get stuck in Nashville or Atlanta traffic, it can be that much warmer. We are conscious of (but not hyper-sensitive to) CCC and we pack our coach the same way each year. For the first two years, at some point in the trip, our rear tire PSI would rise to the point of tripping an error on the Chevy tire pressure monitoring system. That system can only register 2 digits of pressure. Starting at 80psi cold on the rears, our tires were getting to 100 psi during the trip. The third year, we decided to try nitrogen. The rear tires the next two years have never seen higher than around 92 psi.
Snake oil it is not. But you should have a specific reason to use it also.
