Thanks Ken, the TT have been on my list for awhile, just not near the top yet.
My understanding of the rear suspension is pretty sketchy, as you can tell. Now if we could just get Rob to do a detailed procedure for dummies like me on checking them like he did for the steering system, there might be some hope...

If your list includes tru-trackers and the reaction arm brakes they might be incompatible.
Can anyone confirm?

Jay,
Problem is Rob hasn't done much work on the rear suspension (changed shocks,
re-plumbed Powerlevel with new tubing - end to end, and mounted the ride
height control valves on stainless steel plates in the wheel wells) himself
so he needs the procedure himself! ;-)

Jay, one of these days, you might consider getting and reading the Manual on
these GMCs. If you can't locate a good paper version, there are two very
good DVDs out there. Emery Stora has one, and I can't remember who has the
other one, but I have it as well as both manuals and the parts book. It
really is a great help, particularly when it comes to torque specs,
dimensions, and how the coach was originally assembled. Many of them have
been extensively modified, through the hands of several owners, and no clear
trail as to how it has been fixed. Answers a lot of questions for me.
Between RTFM and the GMCnet, there isn't a lot that you can not get factual
information on as well as JWID.

Tom Lins is the fellow who has compiled the DVD
with manuals from 73-78 and lots of info on the
various ancilliary items.
I bought that DVD a good six months back and
printed the appropriate portions out and put
them in a three-ring binder. It's an excellent
product.

Larry,
You're correct. When I put the reaction arm set-up on, I had to
delete the tru-track.
However, I have a solution in mind. I just need a little time.

When at first you don't succeed read the manual? Yeah, red-faced apologies for what might be considered laziness. No excuse, Sir. I actually have an original paper 7525 from the PO, and I also bought the DVD. Maybe I'm just intimidated by them, though I have gotten ride height specs and other stuff from them, so I haven't Completely ignored them...
Thanks for the reminder, Jim.

Jay,
I have a copy next to the bed and that's what I read when I have trouble
falling asleep.
It's amazing how often I wake up in the middle of the night with my glasses
on and the manual in the middle of my chest! ;-)

At this time, Chuck A is running both, but our designer Rick F is not
liking it too well.
Gary K is working on a better way to do it as I sent him some parts
that was rejected from a machine shop as they did not measure up.
Just a matter of time before we will see it happen.
I need to take actual count, but I think we have supplied over 14 units so far.
