Chuck
Is there any problem on this, ie: does it make the torque box bind??
Also, how/what did you do/use for the jacking system that I see
atached on the bogie frame?
Thankx

Charles,
The massive bearing mount Rick designed that is bolted to the inboard
side of the suspension arm and the harden steel bearing is probably
10 times stronger then the bearing I used on my original concept
which I had no problems with several years of driving. I don't think
there is any concern with the torque box twisting. The true track
bearing is only putting a horizontal in and out load on the torque
box I don't know if you noticed the angle-iron bracket has three
different mounting holes for the bearing which is mounted in the
center hole. My intension is to some day mount two true track
bearings,one in the top hole and one in the bottom hole to see if it
helps reduce the suspension arm twisting and maybe reduce some of the
inherent mid axle steering. I get all of my GMC parts free from Jim
so if I break something he will replace it.
As for the 12v dc stabilizer jack you saw in the photo, they are
probably the most useful modification I have made to our GMC. I have
two in the rear and two in the front that have been on our current
GMC for over 20 years and I had the same units on a previous GMC for
5 years. They are RV trailer tong jacks that I got from Camping
World back in 1985 that I modified slightly for mounting on the GMC.
They are rated for 3,000 pounds and have a slip clutch that prevents
any chance of overloading. Manny is the only person I know of that
has copied the concept. There are 4 DPDT switches on my dash for
control. When I go to a campground I level my coach using the air
bags like most of you folks and then put down the jacks and vent the
air bags down and you can't see any rocking of our coach based on
internal activities (don't I wish). The front jacks will lift the
front off the ground but the slip clutch will will prevent lifting
the rear totally of the ground. I have been in only one camp ground
where I could not lift the rear high enough to get it level.
However, they will hold the total weight of the rear.
I use the one on the left rear to do double duty. When I am driving,
I use it to actuate the parking brake (shown on my "chuckieboy" photo
site) to lock the two left rear wheels together. The jack has enough
capability to hold the coach position with the air bag vented. You
don't want to know how I know that. When at a camp site I disengage
a locking lug and it them becomes a stabilizer jack. I store out GMC
in an inclosed area between the garage and a high block wall on the
left side. I have a garage side door that allows entry while parked
but I do not have enough room to access the left and right side of
the MH. When I park it I lower the two rear jacks and vent off the
air bags. When I get ready to move it, I hook my garage air system
to a QD under the front hood and air-up the coach air system.
If anyone has any questions about anything GMC please feel free to
contact me by email or phone.
Chuck who has to much crap on his GMC

I love the idea of the tongue jack. I just wonder if one could be incorporated to actualy lift the rear off the ground to make tire changing and other projects on the rear suspension easier. I do have a J hook and jacks to lift the rear, but having a preinstalled jack would be the best (if it could lift high enough to insert some jackstands under the frame).
As with most things, all it takes is money!

I had a 1936 ALVIS drop head coupe ( British car similar to a Bentley) and
it had 4 built in scissors
jacks also 4 wheel adjustable shocks from the dash,dual ignition, 9 valve
springs per valve etc., etc. Not much
new on cars except computers.

I'll bet it came with Lucas Electrics, and Girling brakes that used mineral
oil too. Probably had those wonderful baulk ring syncronizers that you had
to pause momentarily in the neutral gate or snick the gears. If they were
like most British cars of the time, they had about 3" of wheel travel. Big
ol' long stroke engines and a wonderful exhaust note. British cars have
wonderful flowing designs but the mechanicals aren't on a par with the
styling in my opinion. Worked on XK Jags & those valve lash adjustments
could take you up to a week to get right. Fortunately, after break in and
initial adjustment they seldom needed attention until they were quite worn
out. On the racing versions of those XK Jags, the aluminium fenders and
bonnets were made out of alloys so soft that you could dent them with your
elbows if you weren't careful when you worked on them. I tried to not be too
critical on these cars, I kinda do like them in spite of their quirks.
Nothing sounds like a Jag or a Healy inline six at full song. Kinda like the
exhaust note of a 455 Olds, with that siamese center exhaust port and huge
exhaust crossover, they have a very distinct sound. I love it, some people
hate it. Kinda like the sound of a Harley, you either love it or hate it.

Your right about the lucas stuff, but the Alvis had 2 of everything,2
electric fuel pumps,
coil and magneto ign.,3 su carbs, etc, it even had something from GMC, a 4
speed all syncro trans
that was built under license from GMC (why didn't GMC build one till
what,1958 or so?)

Camping World wants $160 ea for their 3000#, and $280 for the 3500#
But eBay has bunches of them, and lots cheaper, though who knows if they're equivalent quality.
Cheapest 3000# I saw in brief look had a starting bid of $69, offered by T-Motorsports
http://www.t-motorsports.com/
Their website lists the 3000# jack at $73. Looks like it has a manual switch on the jack, while some of the more expensive ones are wired to trailer plugs.
ebay had lots of 3500# versions, including one with a 6" drop leg for total of 24" extension for buyitnow $140 (item# 350422831610). Seems two of those on the rear ought to lift the wheels off the ground pretty easily. They also have 4000# versions for $200+.
OTOH I imagine the mounting might be a significant engineering challenge. One that I looked at (and they're all pretty similar) sticks up 18" above the mounting plate. Love to see some details of how Chuck modified and mounted his.
I'm afraid my wannado list just got longer...

How did you modify the jack for mounting??
Front - Back...Pics?
This may be one of the 'best' items for the GMC..
Its a PITA to jack even to just change wheels
