Replacing aux air compressor

(1/1)

Fred Cook:
Ok, I now have all the necessary components to change out my old compressor. It’s located upfront adjacent to the driver side wheel. The new compressor is VIAIR 444C. I plan to build ramps out of 2 x 10 boards to elevate the front for better access. My only concern is once the coach is on the ramps and release all the air, will I still have enough room to crawl under the coach and.. how safe is it with no air in the tanks? Has anyone ever done this before?

David Ciotti:
I don't build ramps, I just stack 2x12,s to raise the front end.  Usually 3 high is all I need.  I have crawled under there and sat upright to inspect and replace all kinds of stuff.

Thanks for the input. I now have access to a pit allowing me to stand under the coach. Will be getting it done tomorrow night or Saturday if needed.

David Ciotti:
Can I borrow that pit for a day or two?  :)

Fred Cook:
Not mine…. Belongs to a friend of a friend. Really lucky to use it. About five years ago, I was able to rent out a pit from a local business. You may be able to find a local business that would rent one to you.
