So with the first warm day in a while I decided to put the coach up on stands so I could do a little maintenance for the warmer weather, with nearly disastrous results. With the front of the coach up securely I started on the rear. I put the driver side up on a three ton jack stand. No problems. Then I started on the passenger side. I pumped up the bags slipped my stubby jack under the boggie, gave a pump or two then hit lower on the dash switch. Waited maybe 5 minutes. Jacked up the passenger side, put it on a stand. At this point I noticed the coach wanted to go ass out towards the driver side. I went over to the driver side to try to level her out and give it firm footing. This is when the passenger side bag exploded. The whole thing went even further down hill from there with the coach eventually coming down off her rear stands, somewhat gently and without damage.
Now lets forget my piss poor blocking job for a second. Why did that bag blow. Did I not wait long enough for the pressure to let out or is it possible that the valve would not release the pressure. I have had the coach up on stands many time before and never had too much trouble with the bags. The bag that went looked in rough shape; I have a spare.
Secondly is it possible that the coaches frame had some torque in it, as in the rear wheel had not gotten directly behind the fronts when I parked it?
I'll get her back up soon, but man do I hate jacking this thing up.
