Hello! We're heading out for vacation shortly and sadly without the GMC. This will be the first time I won't have a chance to re-inflate the bags so I'm looking to put in some wood blocks under the bogies while I am away.
Apologies but my short search did not come up with a photo of were EXACTLY to place the wood blocks.
I don't want to mesh anything up. Does anyone have a photo or clear description of where to block under the bogies?
I have to run up to the storage lot and don't want make several trips.
THANK YOU....!

Thanks Matt. They’re in place now. I prefer to play dumb (easy to do) with new to me things so I don’t mess something up. Interestingly, my suspension was at full height after almost two weeks. Up till now they would sag after 3-4 days. Bummed we can’t take it on this trip but have lots planned for the Fall. G.

Matt,
Cut a 2x4 15" long and lay it on top of the boggie case and release the
jack,
Since it is not going to be moving much, no need to knotch the ends a
little.

Larry,
What Jim is saying is to cut a 2x4 15" long and lay it on the top of the bogie casting when the coach is jacked or aired up to a good height.
This will put it between the vertical parts of the swing arms. When the load is lowered, that piece will stop the lowering and be trapped in there. This could be a problem with many of the non-OE suspension modifications.
I like this idea, but I have never done this. In my years of moving heavy stuff, we always used blocks or cribbing under the load. So, I usually just air up the suspension and pile my shoring blocks of which I have more than a few around the barn under the bogie casting. My system is now tight enough that I have to let it down if I want it down.

This is the first time I've heard of using a 2x4 block just above the bogey box casting. Trying to get my head around the forces involved.
It seems to me that the ~2000# wheel load acting on the ~18" horizontal bogey arm lever would potentially crush the end of the 2x4 which has to counteract that same load but using a much shorter (maybe ~6"?) lever arm along the vertical bogey arm. That would put the load on the 2x4 very close to the ultimate crushing strength, of say Doug-Fir, parallel to the grain. The curved bogey arm wouldn't present much bearing area initially, but would compress and potentially start cracking along the grain.
Again, first time hearing about this and I have no experience with it and Jim K does. Anyone else use the word block above the bogey box?
If there's no danger of the wood crushing and splitting it certainly would be the fastest way to relieve pressure on the airbags. Blocking under the bogey boxes and relieving pressure on the airbags takes more time, but takes pressure off of both the airbags and tires.

I've got 2 pieces of 6"x6" cut to the height beneath the normal bogie
height. A cabinet handle on each makes it easy to maneuver. When I
installed the Manny Reaction Arms, the center pivot mounting bolt
interfered with those blocks until I cut a bolt-head-width slot across the
top of each. I've never been able to stop ALL my leaks, so those blocks
always go under when I'm parking for a long time.

I also am not understanding how the above the bogey arm blocking works. Ever since day one, 23 years ago, I've just put some 4x4 and 2x4 x ~ 24" pieces under each casting to desired height. I pretty much use wood cribbing to support the coach, rather than jack stands which I think could move, when I work under the coach.

Uh, there's NO WAY a 2x4 would do anything if put on top of the airbags, the bags are significantly bigger than the bogie mounts, even the cones are bigger.
If there was no airbag, then it could work, but I'd rather use a 4x4.
Or maybe you could put something below the bags? Kinda weird though

!5" and when you put in a slight notch , the curved upright will not split
the wood.
I have had several do it as a last resort.
The Q Bag does not interfere, only the Paddle of a anotherdesign, in that
case remove the paddle.
I personally have traveled 120 miles that way.
