View Full Version : Slide Air Leak

04-20-2017, 01:37 PM

I have developed an air leak in the rear slide of my 2006 Marathon. I arrived home after a two week trip and all was well. I put the coach in the shop and opened the slide for interior cleaning. After a couple of days, I closed the slides and noticed an air leak after the slide was closed. It is coming from the lower right corner of the slide. The slide seems to be working OK.

Any suggestions as to were to start looking? Is this an item for Prevost to service?

Thanks in advance.

Make sure your slide seal pressure is set to 10-12 psi so pressure doesn't affect other slides, if the pressure caused the current leak.

There is no Prevost approved method of fixing an inflatable seal leak except replacing the seal. The seal is about $2,500 with labor the job is about $4K.

Some have successfully patched a small leak if it's not in the curve if the tube.

Replacement involves removing the outside upper panel that extends above the slide. Then the slide is retracted into the coach just far enough the remove the seal.

Good luck,

Had 3 slide tubes replaced no charge due to defective manufacturer. This was 7 years ago however.

Thanks, Gil. I am making a trip to Texas for repair as that is the closest Prevost Service center to me. $4,000 was less that I expected.
