Not a lot of progress lately.
I did get the chance to yank out the head unit and replace it with a small bluetooth amp I designed,(used to make bluetooth speakers)
Today my Nexus 7 arrives and I'll be setting that up to run a custom ROM for the GMC.
I came across a product called Chariot Gauge in my searching and bought one. It's a wireless gauge system that will allow me to run Wideband O2, Boost/Vac (MAP), Oil Pressure, Air/Coolant/Oil Temperature, and Voltage gauges on the tablet in dash without having to add the physical gauges. Mike over at chariot gauge shipped it out the same day they came back in stock for me and was pretty interested in the GMC project, seems like a great solution for us without an OBDII port for some cool wireless gauge action.
https://www.chariotgauge.com/
Also got a glowshift dual needle air pressure gauge with electronic sending units to monitor the pressure in the bags.
The plan for the dash is to keep the original instruments, move the air conditioning control to the old electrolevel panel, and install the air gauge and associated switches in the dash along with the Nexus 7 tablet for GPS, gauges etc.
I hope to get started on that tonight! Should have some photos soon.

THANK YOU Sonic !!!
I've been looking for an app like that for quite a while now...
I just purchased the controller and downloaded the IOS app.

Justin,
I'm curious as to why you want to monitor the pressure in the air bags.

Rob,
I don put a lot of faith in the auto level system nor my 40 year old solenoids.
As it stands if I change the height setting for maintenance or for some other reason I have to set it to auto and the for piece of mind get out and walk around the coach to make sure the bags look like they should.
With the gauge I'll be able to just glance at the gauge and be satisfied that all is in working order and I can hit the road.
It's really just for my sanity

Justin,
Problem is the gage readings will vary depending on the load, the ride height control valves set the distance the GMC is from the
ground, the heavier the load the higher the pressure required to set the distance.
You will learn what's normal and what's not.

Agreed.
When the coach is finished the weight should remain fairly constant, so I will get it on level ground, level it, and note the air pressures.
A quick glance at the gauge will then give me the all is well, or let me know something is wrong.
I assume the gauge will move quite a bit on the road as I hit bumps etc and the pressure changes, but it should give me the baseline and the peace of mind I am after.
We've worked a good bit on the coach this weekend so I'll update.
We tore the whole dash out (what a chore!) The PO broke all the mounting points on the windshield side(assuming becuase you cant get the screws out without removing the windshield WELL DESIGNED GMC (not))
Once the dash was pulled we cleaned it all up well with mineral spirits and set about making it pretty.
Fist up we pulled the dash pad off and removed all the pieces.
Then we recovered the pad, the under steering wheel piece, and the part behind the gauges in marine vinyl.
We then painted the rest with 2k urethane flat white with a flat urethane clear
Everything turned out great except the under steering wheel trim, it has some extreme curves and the vinyl has pulled in a few spots, so it will likely be recovered.
I went ahead and cut the Recirc door and fabbed up a stainless plate to cover the original inlet while I have the dash off.
From here I hope to get some wiring done for the Nexus 7 in the dash while I have it off. I need to wire in 3 usb ports with 3A power supplies, 1 for the tablet and a hub for associated goodies, and two to be run to remote USB hookups on the driver and passenger armrest (door panel? ha)
I also will wire up the chariot gauge (got it in the mail this morning).
The dash face will be redone with Black walnut, and I'll make some new trim pieces out of walnut as well for the AC outlets on the dash.
Stay tuned for more photos!
I'm also keeping a running budget tally if anyone wants to follow along:

Hi Justin,
I love your updates. For future reference, it would be *grand*, if you
could upload the pics to http://www.gmcmhphotos.com/
That way, even future readers have access to your pictures.

Jim,
Ditto!
I had the ones in Double Trouble replaced at a GMCMI Convention, one was cracked and I filed an insurance claim for it. Somehow the
insurance company screwed it up and paid me for BOTH of them!
While I am usually scrupulously honest in this instance I didn't tell them! :-)
The installer noted that the problem occurs because over the years dirt get into the seal and works it way to the bottom, when I
rains that dirt get soaked with water and holds the moisture which in turn migrates into the "plastic" sandwiched between the glass.
He was right (naturally) you should have seen the amount of dirt I got out of the bottom of that seal on Double Trouble!
The last thing the installer did was to squirt black RTV between the seal and the glass all around the windshield, it will make
replacement more difficult, however, it will stop dirt from getting in there and fogging the new windshields.
BTW if you have your windshields replace you will NOT believe how much clearer they are than the ones removed! They have been
"sandblasted" for 40 years!

Rob M.

Yep, take it to windshields "R" us and put in new ones. That is what
happens to sandwich glass after 40 years of weather exposure. I don't know
if the following is true, but I have been told many times that painting the
edges of new windshields with urethane sealant before installation will
minimize that effect. Mine are just starting to do that. They are original
and both sides have rock chips and sandblast effect in them. Prime for
replacement.
Jim

E-Mail from Chariot. Tom, MS II
Thanks for the kind words! I love that it's being considered for use
in GMC motorhomes - what a cool application! The tach addition is
almost complete. We have a working prototype that were still tweaking
a little but we should have the next iteration of the controller
available in the next month or so.
I'm not sure we'll have a second input for temperature, ideally we
would have an input for a thermistor type sensor (which is already on
the current controller) and a thermocouple type sensor but I'm not
sure the thermocouple is going to make the cut for the next controller
yet.
Either way, I'll keep you in the loop when the next controller is
ready for production.
Thanks, Mike

[quote title=SONICJK wrote on Tue, 21 July 2015 18:34]Got the dash mostly finished up today. Still waiting on the switches to fill the holes.
The surround will be recovered to match the rest of the dash.

One of my Onans was hunting after I got it running, and no adjustments would correct it. Finally I noticed the throttle shaft was loose in the bell crank that was attached to it. The way I fixed that was to use an automatic center punch to swell the throttle shaft inside the bell crank. That made it a solid connection again, and the hunting ended, allowing me to make correct final adjustments to the carb that I probably screwed up to begin with when trying to fix the hunting!
