I keep some 4x4s below the bags to keep them from going down the whole
way (my system leaks a bit...)

Too high and there’s risk of hot-dogging, where the bag takes a permanent
set in the curved shape. Too low and coach rests its weight on the shocks
(which are at full extension).
I rest mine on sections of 4x6x24” pressure-treated lumber made to use as
posts for decks. I orient the long side vertically so that the coach rests
higher. I don’t put the system on lower—I just let nature take its course.
I’ve never been able to completely eliminate the leaks.

My vote is to air them all the way up, block the rear end up and let it
settle on the blocks.
Unless your coach is better than mine you would have to run the compressor
at least once a week to keep the coach off the ground.
I would also block the front end to eliminate weight on the front tires.

It is not good to have the suspension collapsed without the air in the
bags. They wrinkle up and a good deal of weight is applied to the wrinkles.
Better to raise it to ride height or slightly higher than that, then
block up under the bogie boxes enough that if you lose air, the weight of
the coach is supported by the blocking.
If you are a belt and suspenders kinda guy, block the tires entirely
off the ground as well, and wrap them in such a way as to shield them from
harmful ultraviolet radiation. (Sunlight) This will prevent flat spots in
the spring when you wake up the coach from it's long winter nap.
Here in Oregon, we have rallies year around. So, not much
weatherization is done. Only for 3 or 4 weeks a year does it even get cold
enough to worry about frozen pipes, tanks, etc.

Our GMC's have alway been under cover when stored for the winter and a
cover to keep the sun off the coach in the summer time.
http://www.gmcmhphotos.com/photos/g3851-rv-cover.html
Since moving to our new place in 2004 I have had a large pole barn to put
all my "STUFF" into.
In all my years of storing the coaches thru the winter season (1998 thru
2005 & 2018/19) I have alway put blocks un the middle of bogy assemble.
The blocks are 8" tall, The blocks are NOT used to support the coach if
working underneath the coach. I have always stored the coach longterm with
the air out of the system. At this time i clean the air bags with 303
Aerospace Protectant that cleans the air bags and provides UV protection
for the following season.

The original bags are three distinct layers. The inside layer is a soft
neoprene of military specs. The middle is a fabric, not unlike fire hose.
The outer layer is an extremely tough, durable, u.v. resistant neoprene.
Also military spec. Why military spec, you might ask.
Because those bags were developed to support the nuclear blast proof
buildings inside Cheyenne Mountain. Really good stuff. So, the outer layer
protects the inner two. The innermost one holds the air. Most of the time,
when you suspect a bag leak, it is at the end where the air valve is
located. It is usually a "0" ring that has worked loose or deteriorated.
Those fittings are a real bugger to loosen, but usually will yield to
persistent effort. The "0" ring is between two flat surfaces that each have
a partial groove machined into them. That "0" ring has to seat perfectly
between those plates, or they will leak. So, bubble test that juncture if
you suspect the bag is leaking. The bag will need to come out to replace
the "0" ring. Just what I know.

Rich Mondor,
Brockville, ON

One additional comment. When I put the support blocks (8" tall) in the
center of the rear bogies, I raise the rear end up by increasing the
pressure in the system. I then let the air out and the coach level is near
stock at rest with the blocks in place. The air bags look like they are
supporting the coach and they are not deformed.

In my "vast" years of experience (3 winters! :roll: ) I have put blocks under the bogies and then lowered it a bit until resting on the blocks.
Didn't start from full inflation, just a bit above normal ride height, placed blocks to a height just about an inch below the bogies then lowered
until I was unable to shift the blocks. I have shut offs in the air lines so they stay pretty stable, but over a 6 months winter, I just thought it
was nice to keep the weight off a bit, and also keep my shocks happy.
