SCUBA tanks for filling RV tires?
I have a vague memory of some folks getting a SCUBA air tank pumped up to very high pressures, then carrying the tank (with a pressure regulator) to quickly and accurately fill RV tires. Do any of ...

In addition, to use a SCUBA tank you'll need some type of VERY reliable pressure regulator which limits the fill pressure to about 150 psi. The standard SCUBA regulator won't work because it's based on the ambient pressure plus what is needed to compensate for breathing at any given depth.

Every regulator I know of works with relative pressure (absolute-ambient). The 1st stage of a SCUBA regulator limits it to 120-150 psig. The second stage drops it to zero relative pressure, which won't help much with a tire. Even 150 might make a tire go boom, but you will have much more control than trying to use tank pressure.
