Here is my situation. I tow a travel trailer on extended trips, often disconnecting for a few days at a time, and then driving my F150 on forest service roads and dirt tracks, as well as on pavement. This means I spend a lot of time airing my tires up and down, and I carry a Viair compressor for these duties. I know ARB and others make devices for deflating tires to a specific pressure, but does anybody make one for inflating tires to a specific pressure? Something which would allow me to connect my compressor and walk away without fear of overinflation. Any advice would be appreciated!
