After 3 days in storage, I now notice that the coach has a slow air suspension leak on the left side. So, until I'm able to diagnose and fix it, what is the preferred way to block up the rear? I want to depressurize the bags during storage anyway.

Also, would there be any harm done if one side leaks down completely before I get some supports under it?

Thanks,
Pete.

It won't hurt anything to let it sag all the way down--other than your pride Smile However, many people place 4X4's or some wooden blocking under the center bogie support. Do not use concrete blocks since they can disintegrate.

Pete,

As someone with damaged wheel-wells....

Depending on the year and maybe tire size, it is possible to do damage by allowing the system to go all the way down. 1973's and 1974's would rest on the PLASTIC wheel-wells and cracking them. Larger tires make it even worse. They changed the wheel-wells and the boogie castings in 1975 making this less of a problem. (I am not sure if larger tires could still damage 1975+ wheel wells.)

I use 2 4x4's about 12 to 18 inches long under each boogie. (Total of 4 for one coach.) Depending on where it is parked, it might need a 2x4 or two to get it level enough to run the propane refer.

As a side note: If you put your coach year and model as well as your location in your signature line, you'll end up with better advice... "odds are" anyway.

Pete,
I can attest first hand to what Mike said about the damage that can be done to the plastic wheel wells on a '73. Ours are cracked on both sides, apparently from settling. I had planed to post a question to the group to see what is the best method to repair them. If someone has a suggestion please let me know.

Replacement would be difficult unless you have access to the full inside... ie: almost gutting the coach. Repair is the only option for most of us. I tried fiberglass and it doesn't stick to the plastic. I needed to use the coach during the wet time of year (10 or 12 months here in the Great North Wet.) and did a "temporary" repair with "Right Stuff" in the cracks then painted over with black paint. It seems to be holding. (Keep in mind I really do not use that coach right now.)

BUT...

The best repair would be with plastic welding. (I have been learning on the front wheel-wells.) I am thinking I would cut and weld (adding material) to clear the largest tires I have, when all the way down. Kind of line the fiberglass wheel-wells in the newer coaches.

I built a platform of 4 x 4 's that is about 4 sq ft. I put this between the rear wheels, and set additional 4 x 4 on top to join this together. I then lower the coach until it rests on the wooden platform. My goal was not to support the coach, but to spread the weight of the rear of the coach over a greater surface area. This is intended to keep my asphalt parking pad from "denting." Coach is rock steady lowered onto the platform.
Takes just a few minutes to inflate the bags and lift from the resting place.

A 4x6 pressure-treated post from Home Depot, which is made for building
decks, will work fine. Stand it so that the 6" dimension is vertical. It
will slide under the bogie frame at normal ride height, but it will not let
the coach down to the point where the tires will rub the fender wells.

Only if you have an early coach. If the tire touches the wheel well,
cracking the plastic is only one possible issue. It will also lift the wheel
well off the floor, creating a leak that will allow water to enter the coach
at floor level when you drive in the rain.

I replaced the top of one wheel well with galvanized sheet metal. I glued it
in place with 3M 5200 and screwed it to the plastic every two inches with
self-tapping screws.

The other one isn't in such bad condition.

If you have a '75 or newer coach, it couldn't be a problem.

Keep an eye on the cribbing, I had a 4x6 fail along the growth rings. It fell apart after relieving the pressure. Not a good feeling.

Thanks everyone. I'll head over to Home Depot this evening to get a couple of 4X6 posts. Even though the '77 won't be damaged if it sits down, I still want to keep weight off the bags while in storage. Not sure what arrangements the PO had for storage, but when I asked he claimed it "stays up forever..."

Ha.

Pete,
We supply the Air Bag Isolators that will hold up the rear as long as the
bags are not leaking. Also there is a Schreader valve so one can fill it
should you sever the line or compressor failer.
It's on our site, we sell lot of them.

Well frankly Pete, knowing your coach is a 77, I'd just let it settle. There will be no adverse effects on the bag at all.Propping it up won't do or help it in any way.

I use a jack stand under the receiver hitch as a "tail stand". Actually any time I get out for more than a few hours, I stick in the tail stand just in case a bag lets go I got something to catch it and have some hope of jacking it up. I've gotten under there to see what the hitch is connected to and it doesn't seem to hurt it.

Yeah, that's what I was thinking later. My main concern was that it didn't lean over against the garage wall (it's pretty tight in there currently), or overstress any other components. I'll let both bags down tomorrow - gonna be a couple weeks before I get around to dealing with it.

Thanks again.

I am surprised that the hitch will hold 8,000 pounds.

I slide blocks under the bogies every time I park in storage, takes the load
off of the air bags, and I can slide under for a look ;>)

Got a real job, working for the gubmint. Lots of travel, limited access to
GMCnet on the gubmint computer and following (appropriate, of course)
gubmint policies, and work that needs doing the moment it appears, making it
hard to goof off and make up for it later.

Me too, but it has for almost 3 years. The load seems to get spread throughout the hitch assembly. so maybe that makes a difference.
