Air Bag Pressure While Not Rolling

My MH has air bags inside the front springs. I set them at 90psi when travelling, but what psi should I set them at while parked/stored for long periods during the winter. ???
I have the leveling jacks all the way out, and couch is level.

I see no reason to deflate the air bags. They are spec'd to have a range of air pressure in them. As long as you are in that range, you are OK. A completely deflated air bag can be damaged when the MH is driven and when a bottoming of the suspension occurs, so keep some air in them.

If they are inside the front spring just for assist and not the only thing holding the vehicle up I would suggest leaving 5 psi in them.

This is what we recommend for all of our Air Lift kits. This ensures that the bag does not come dislodged from where it is supposed to be. It also helps the bags maintain their shape.

I would check your manual though, they may recommend something slightly higher such as 10-15 psi depending on how stiff of a wall the airbag has.

There is also a lot of good information in this thread:

Interesting view about dumping the bags

That thread is more driven by people with only air supporting their MH, but some of it may relate to your questions.
