Level raise with slide out?

Since going to Roger Engdahl manual leveling method....i quit auto mode...i leave aux compressor off, just works for me.  Some disagree, auto better.  Ok.

Now that the coach has settled on down after a month, i need to raise it to start the cycle over of slowly going down.  (Did that in auto too)

Is it ok to crank and raise the coach with the slide out?

(I think i have seen the rv shop move thevslide in and out when coach was not close to level)

Michael,

I'm not second guessing you, but just curious why you think it necessary "to raise it up and start the cycle over".  Why not just let your coach sink down to the hard stops and sit there until ready to move it again?  Unless, of course, your parking spot is very much out of level, in which case I understand your motivation.

I always heard that starting the big engine and running it for a short time (like, for instance, just to raise the coach) was to be avoided whenever possible.

Personally, I prefer to use my on-board 120V air compressor (equipped with copper tube cooling loop and water separator) to pressure up the air system when necessary.

Mike, four ways to do this.  You can adjust level with the slide out but the transmission will be locked out so you can't move the coach.

1. If you are in manual level mode and the small compressor has power pressing an up button or the raise button will start the small compressor.  If your HWH tank is out of air then it will take a long time for fill it to the necessary pressure (90 psi) to raise the coach.

2. Starting to coach will air up the wet and service tanks but not the HWH tank.  With air in the service tanks you can rise or level the coach.  Probably not the best idea unless younre going to drive it for 20 minutes or so.

3. You can add air to the wet and service tanks with an external compressor with a simple modification.

4. If you connect an external air compressor to the aux air connection you will supply air to the leveling manifold and can level or raise the coach. Air will not be added to the HWH tank or the service tanks assuming your check valves are working as they should and the plumbing hasn't been modified

Or just let it rest where it is.
