Come on folks, the OP asked a legitimate question and is simply in search of N2. A helpful post would provide him with some guidance toward the end result.

N2 is NOT bad. It's dry clear air and will do no harm and may (as the OP indicated) allow you to avoid having to air up the tires for longer periods of time than would be expected with 78% N2 (compressed air).

I agree. The OP asked where he could buy N2, NOT for a discussion on it's merits.

If he wants to run N2, that is HIS choice, and should be respected.

If you wish to discuss the merits of N2 again, start a new thread.

WHY?
Wants wrong with just 78% nitrogen and use regular air vs all the hassle and added expense of nitrogen. Especially when you can't even find a place to do it.

My new OR came with nitrogen filled tires and I put my pancake air compressor back in the TT for air ups. I haven't even checked for it in my area but I suspect that it would be hard to find. If I was bent on having pure nitrogen replacement I would go to the local AirGas supplier and buy whatever I needed to do it. My best guess is that would be the most prudent way to ensure a supply. YMMV

After spending 36 years+ in the welding supply business I would have been elated to find a bunch of customers who wanted to buy tanks and regulators to use nitrogen in their tires. As the end user I would have felt that I just got the biggest screwing of my life.

I wouldn't call nitrogen use "snake oil" because there are legitimate uses where it is actually useful, aviation and racing already being mentioned, but RV and passenger vehicles is really questionable. We used it in our fleet vehicles because it was very low cost to us and we didn't require an air compressor for our air needs.

That being said, I actually carry a 40 cf tank and regulator with a delivery range of 400 psi in my motorhome for exactly the purpose being discussed. When at the home base I use my compressor to maintain the tires pressures and the N2 tank on the road as required.

To the OP, do what makes you happy and comfortable, after all it is your choice and your money.

Airgas has locations all over the US. I would suggest you purchase an F size tank and regulator. Otherwise they will charge you rent on the cylinder. This can be easily carried in the MH safely. And yes I used to work for them.

IMHO, is a waste of time and money. Aircraft of course, racing maybe, all others No, this was a gimmic based on a aviation model that has no place in over the road anything!

If you are not able to find a N2 source near you, be sure you use DRY air. If you have an air suspension coach with air dryer, that is quite acceptable (and I am picky)!

Dry air and N2 both follow the ideal gas law (i.e. PSI change with temperature change). It is air with water in it that can mess you up.

Yes

But N2 also follows the ideal snake oil law. :S

It's best you get it from a professional. Some people have resorted to getting the stuff from seedy characters of dubious intent selling it out of the trunks of their cars in back alley's and end up with only 78% N2. Lives are ruined and all that's left are the tears.
