I need to get to the shrader valve on my air bag suspension which I believe I need to remove the t skirts to get to the valve. Can I just undo the
two top screws and pull the skirts back?

If your T skirt is standard, you can.
Be sure to apply some thread sealer on the fittings to avoid leake. Not all
have the valves as they were put on by the owner.

Short answer is, yes. But only a couple more screws/bolts and you will be free of all encumbrances.

Jeffery, in the amount of time that you spent asking that question and
waiting for the answer, you could have removed and replaced both sides and
inflated the bags. Jus' sayin'.

Jeffery,

The T-skirt is held on by those two top screws and the flexible attachment at the bogey mounting box. It's usually easiest to remove the bottom
attachment by removing the one bolt that holds that flexible attachment to the top of the bogey box.

People ask questions because they don't know the answer and are outside their comfort zone. If you have a question, ask it.

Exactly. Even the simplest of things can seem complicated if you've never done it. Also, mechanical skill levels should be considered...

In my opinion, there are no stupid questions here as long as they have something to do with a GMC. If you have never done it before, and in my case
even if you have done it before and forgot how, then ask away.

Jeffery,

You do know that most of us here were born knowing everything about GMCs that we needed to know - Right? ;)

All seriousness aside, you asked a question because you were unsure. Because you didn't just jump in and break something, you have nothing else to
repair and no parts to locate. That is about as good as it gets.

This is an open forum (anybody can read it). There are even some owners that read this forum but never ask a question. So, when we answer your
"stupid" question, there is no way to know how many others just got their question answered. This was driven home for me at an international years
ago. Someone was there and he looked at my nametag and I could see that it brought him to a short halt. He then told be that he had read something I
wrote, but was hoping for a clarification about something. I was fine with that, but I also asked why he didn't ask for that here.... He just
shrugged. He sure could have.

Be aware that many that write here have so much experience that they (well, coach-wise I am way behind them) tend to skip some points that might
matter to someone with less experience. So, if you get an answer that you don't completely understand, SAY SO. Add it to the thread.

This group is clearly not the norm for RV owners. GMCs just don't attract people that don't feel they need to understand things. If you want a to
see this, I recommend reading entries over at and and don't have anything there to drink that might be uncomfortable to snort
out your nose....
I really mean questions like:
"Why do the A/C and microwave stop when we unplug from shore power?"
"Do I have to check the pressure of both rear tires?" (He was referring to duals.)
"I can't keep the lights on unless I run the engine."

So, please keep trying to ask stupid questions.

Lol thank you Matt. I’m sure I got plenty of them, but I appreciate your kind and encouraging words. I tend to like doing my own car repairs ,
mostly of German decent, so this ride can be somewhat daunting. My drivers side airbag is behaving like others I’ve had experience with ,Audi all
road and range rover , in that when it gets beyond a certain deflation point it’s very difficult to inflate . Had them both fully inflated yesterday
. Finished them off with coach compressor and all seemed well . Drivers side was down flat this am. Guessing it’s time to replace

Jeffery, get a bottle of childs bubble stuff, put it into a spray bottle.
Inflate the bags by the Schrader valves and then turn off the valves. This
isolates the leak source to the bags and fittings. Spray the exterior with
the bubble stuff, and watch for bubbles. Places to be watchful are the
Schrader valves, their pipe fittings, and where the air line screws into
the bag. Let us know what you find, and we can go from there.

Jeffery,
You need to understand there were many people reading your question and
learned from it.
Youll find me asking questions than lot consider basic, but that is how I
Know the better answer and not some BS comment.

Please do not be in a hurry to replace that air bag. There are lots of other places where the leak could be in the air system. While diagnosing the
leak, air it up and put a block of wood (A stack of 4x4 or 2x4 cutoffs a foot long or so would do) under the bogie to keep the coach from going all
the way down when the air leaks out. As Jim Hupy said in his previous post, isolate the bag from the rest of air system, air it up, and go after the
leak with soap bubbles. Once you find the leak, we can talk about how to fix it.
