So the question about can you run a 1" impact from the coach got me curious.

Here is the data on a little experiment I ran. The short answer is yes. The longer answer is that with a 1 inch Klutch (northern tool) gun on a 1/2 inch airline with 1/2 inch quick disconnects the gun would remove or install exactly ONE lug nut before you had to wait two minutes for the engine to charge the air back up. So, you would take twenty minutes to remove ten lug nuts. Much quicker to break them loose with four ft bar, and spin them the rest of the way off with a 1/2 electric impact wrench.

I know, I know, but inquiring minds wanted to know.
