Unless your RV is powerful enough to accelerate to 150 mph in about 2 miles with a dragging brake, and can then fold its wheels into an enclosed box, you don't need to waste your money on nitrogen. If you can get it for free, it has a few very minor advantages.
Dry nitrogen servicing is required on aircraft tires for the following reasons...
1. It's dry!
2. Nitrogen does NOT support combustion!
3. Required by aircraft manufacture's Approved (FAA, EASA, etc.) Technical Publications!
For auto/truck/trailer use... what a scam!
