What is the best portable tire inflAtor for big RV tires

I have the Viair and like it. The only drawback is it is still slow. I think if you could rig up a small tank it would help. I use it on the toad and to top off on the coach. I found out how slow it was trying to pump up someone else's  Big RV tire. I also have a  pancake compressor now.

I have Porter Cable, also.  I installed another chuck directly to tank pressure of 150# and use 50ft 1/4 air hose. To top off the large motor home tires, pressure is needed.

I would recommend using the 3/8 air hose because it flows much better. The Viair works better using a 3/8 hose it just isn't as compact.

On a Spartan chassis, the instructions say to plumb this onboard air supply line into the wet tank

Ray, what?

Ray, I am with five on that. Yes you can but it is such a pain to do. One of the You Tube channels made up a device to use to do it. It had a valve so you could blead down the air and get the compressor to start and provide usable air preshure. Outherwise when the preshure leveled off above the start point for the compressor you had to go pump the brakes to lower it to get the pump to start. 

One outher thing make shure you have a air fitting that fits the hoses you are carryings. The one by the generator is not compatible to standard air hoses. There should be a male fitting secured near the female fitting. This is so a tow truck can air up the system and release the brakes if needed. I made a adapter incase I wanted to use it.
