a hydraulic jack ?
Is it OK to park, air down, WITHOUT jacks down? Some areas in my travel where I park are level enough but on gravel/grass. Often one or more jacks may just sink into ground due to so much weight of coach. I continue to use jacks although they may be doing little to stabilize MH, and are bunching holes in the RV "pad" area. Am I damaging anything regards to MH to NOT let jacks down?

If you have a slide out just be sure you are fairly level before extending. We did this often with our Georgie Boy. The only negative is the movement inside the trailer(back and forth rocking) which is not that bad

The answer is in the fact that not all rig's even HAVE power jacks.

Thanks for replies. I was not even thinking about slides when I posted, but I would generally want all extended. Not really knowing the air bag system, mechanical and otherwise, I did know if setting on deflated bags harmed any part of air system. My thoughts were that perhaps hydralics "eased" the load on the system.

a hydralic jack cautionary note
We do frequently park our 38' Newmar Dutch Star without the jacks down since most campgrounds have level pads. But we do not extend the slide-out. The previous owner extended it without the jacks down and the windshield cracked in the opposite corner of the slide-out from the stress. Coach still passes inspection because crack is not in driver's view.

I wouldn't air down without using the jacks.
This could twist the frame if the parking area is less than perfect.
The jacks are made to accomodate a less than perfect parking spot...
The suspension (aired up) of course it is.
Sitting on the bump stops... Naa, not so much.
I use playwood pads under the jacks if they will need extra support.

Use jack pads that is what I do
I don't air down without jack support as it is hard on deflated air bags for 20 tons to rest on them

Good point. when using jacks, you do air down, correct?

Oops, I did not word my question as I meant. Do you air down before lowering the jacks? I read one of the posts as though some might set jacks before the air down. I just assumed one should air down first, but maybe no.

On our new coach, we have single button leveling. This lowers the coach and then levels using the jacks.  I would assume that is why they (HWH) programmed it that way.
