I guess since the front airbags leak down slowly and yet hold air, there is no air once the genset airbags have depressurized and the air line has no pressure

This statement confounds me to no end. How is it the airbags leak down slowly and yet hold air?

And there is no air once the genset airbags have depressurized and the air line has no pressure, also confounds me.



First, the six pack isolates the air bags from everything when parked, UNLESS you leave the coach in autolevel mode. Are you leaving the coach in autolevel mode?

Are you leaving the 120V on?

To noodle this out, we must draw an obligatory line at the front six pack. All leaks downstream from the six pack to the front airbags will cause the coach to drop over time. We draw this line to emphasize the six pack ISOLATES the suspension airbags when parked.

All leaks upstream from the six pack will result in the systems losing pressure and cause the 120V pump to run.

Hi Richard, sorry for the delay. Ok, maybe I am not saying this right. I am still a newbie to this    So in speaking with Leo he did tell me that one front airbag fitting has a slight leak that creates teeny bubbles and thinks that is the issue for the front going limp after about 12-16 hours. He didn't have a specific wrench to get in there and has since ordered one. It teeters towards the passenger side. I was thinking the front airbags were somehow interconnected to the same air storage tank up front that supplies the generator airbags. I was under the impression the 120v compressor fills that same tank and has a check valve near that tank? I know there is a check valve at the  front 120v compressor. Over the weekend, I installed new airbags, pressure regulator and air lines for the genset. I also put a shut off valve to isolate the genset. It has not lost an ounce of pressure over the 26 hours I had it cut off from the "wherever" the source of air comes from. By the way, the rear stays up on it's own without the compressor's help. That was resolved with new tag bags.

I guess before this gets too deep, I will be taking the coach back to Leo in January to look at replacing the fuel lines as they are hardened. He will address the front wheel airbag leak again.

In answering your questions, if I leave the 120v compressor on full time, Coach stays up and happy. Compressor cycles every 22-25 minutes. it was on a 20 min cycle before the genset airbag replacement. (I did find leaks at regulator and two fittings prior)

If I leave the compressor off, front end will sag to the core of the earth. Genset will stay floating if I leave the cut off valve shut. If I leave it open, it too, will deflate.

So before I waste anyones time, let me see if Leo's repair helps. He says the bubbles are really tiny which in my mind should not be enough to lose that much air but what do I know? Leave it to me to clean up an interior and engine bay. That's my specialty!

As far as auto level goes. I am not sure how to tell if it is set to auto level. When I push the "air" button on the pad, I can manipulate the coach to what height I want and before Leo did any work, the coach would sag on all fours to Mother Earth regardless if 120v compressor was running. Now it stays put even after the keypad turns the red "air" light off. Please go easy on me, This part of the deal is foreign to me!

At the end of the day, I do feel major progress has been accomplished since I became the caretaker of this coach. I had no idea how fongoliated this thing was. Previous owners were in their mid 80's and just paid whatever shop could work on this. Much of that previous work, I cleaned up. Electric tape, zip ties, silicone caulk for glue, an abundance of air leaks, plumbing patches... It was a mess. I do not blame the owners but rather feel they were ignorant on writing checks and never actually seen what was done while they scooted off to their next destination. I guess I can understand in a way. They did love this coach from all the notes we found.

Pictures for posterity

Spray the 2 low pressure switches on the back of the front six pack. Mine were coming apart in the middle and leaking air, which made the front go down over time.

Thanks Ron. I did go through those as did Leo. He is adamant there are no leaks on the underside aside from a tiny micro bubbling action of one front airbag where he could not get a fitting tightened down enough. (Needed a specific wrench that he had ordered and will use when I return in Jan for other work)
