In researching air bag replacements I found this information for my 2005 (04 build) 36 ft Monterey Quad slide.
My air bag has the markings of 566-22-3-143, below are the cross reference numbers and links to sellers.
Neway - 90557121 
Goodyear - 1R11-166
Bellows - 566-22-3-143
Firestone 9295

Beaver Coach Sales quoted Part # as BCS6991 which must be an internal part # at $325 each. A little steep.

I called the helpline at FindItParts to make sure the part I needed was properly cross-referenced and purchased the correct airbags/airsprings on the first order.

Are you sure your bags need replacement, Michael?  Usually it’s line fittings that are leak causative.  Quick-connect fittings commonly used by the factory don’t seal as well as compression ones.  Many here have replaced theirs accordingly.  It’s far more rare for the bags themselves to be leaking.

Thank you Joel for the insight!
My RF rear bag has a cracking on it and when I sprayed it with soapy water I did get some bubbling. I stopped there, BUT now I will now go over every connection with the leak test and confirm!
For that reason I wanted to change the front ones, do you think I should change just the one or all 4 front ones??
Thanks for your help!

I’ll leave that answer to others here with experience replacing bags.  Previous threads here often relate bags with some “crackling” on the outer skin that’s considered normal.  But if you got soap bubbles of significance that’s not good.

Michael,

If you are getting leaks out of the bags themselves then it is time to change out all the bags in my opinion.  I had one bag blow in my driveway and replaced all 8 bags with the Goodyear bags you listed. 

In my case there are only about 2 bags that are easy to get to, for the rest you need to remove the tires and the inner fender plastic that covers the tires to get to the bags.  After that it is pretty straight forward to remove and replace them.  It is actually a job I hope to never do again, but sometimes it is hard to get anyone to work on anything around here.
