Using Entegra 2020 coach air system to fill coach tires

[KenZ71]

I used this post for inspiration to add some steroids to my on-board air

Huge thanks to those who contributed what worked for them.

Used SMC 1:4 from ebay

Only need a few items from this kit: Air Coupler and Plug Kit, 1/4-Inch NPT Air Hose Fittings and Compressor Accessories but Home Depot wanted much more for just one fitting.

and a "Air Leader Hose"

When airing up the bus tires I open the ball valve leading to the SMC, set the max pressure to 150 & git er done
