Wow, I like to read these postings but maybe they should be broken up into makes of RV and gas/diesel. I told my wife after we had been seeing the maps on back of motorhomes with the states filled in by color, I told her those maps must be the sates that they have broken down in!
For a $2.00 part in your tool bag this might save some time. We had a left rear air bag failure. After being on the phone with HR (no help) we were painfully aware that we were 80 miles from anyone to fix our problem. When we called around local no one wanted to even work on a "Roadmaster" chassis. We were quoted 1 to 2 weeks.
After climbing under the motorhome for a couple of hours learning what did what, I determined that the air bags were good but the "air switch" that tells the air to fill or let the air our was bad. You are not supposed to run this chassis with a bag down, especially the rear because of the drive line.
I went to a tractor supply place, (any auto parts or Walmart will have them) and bought a female air chuck like you use on a air hose. The air bags have a "T" at each wheel well because they split the air going into the two bags. When you take the "T" loose it leaves a 1/4" male fitting that screws right in to the air chuck. Take a hose an air it up to be level when the other bags are up. It got me 80 miles to the service center, I could have finished the trip. The motorhome was under warranty but they would not tow it.
The biggest problem was, it was Friday and we got to the service center after hours and they were closed on Saturday, diagnois was on Monday, part was flown in on Tues.
