William,
I agree with Mark that the true tracks are one of the best things you can
do for the steering. And that only the middle suspension arms need them;
I'd even argue that the rears should NOT have them so there's some
compliance left in the tandem system.
I don't agree that they're difficult to install. Aside from reaching the
bolts behind the tailpipe, it's almost a trivial job.
I installed them long before Manny developed his reaction arm system, on
which they're a very economical option. When I did that upgrade, I found
that I didn't even have to change the frame-mounted guides -- Manny's cam
followers on the suspension arms fit into them perfectly.

Get 2, just for the Middle Boggies. I agree that the rear-most boggies just follow everyone else.

Manny's "reaction arm system" is more commonly known as "Manny Brakes".
Here's the link to Manny's web site:
http://www.mannystransmission.biz/products/
Here's the excellent installation manual:
http://www.machinesoflovinggrace.net/gmc/brakes/
That is a much more extensive modification than the true tracks since it
includes disc brakes for the middle and rear wheels; and, most importantly,
eliminates the GMC's propensity to "pole vault" over the mid wheels during
hard braking.
While the Manny Brakes drastically improve the braking capability, they do
nothing for the steering stability of the coach -- UNLESS the optional true
tracks are included.

I just wanted to confirm that I'm a bonehead... I just realized that I actually installed the Straight Trak devices, NOT the True Track devices. That explains the disconnect between my impressions on installation and others'.
I'm guessing that both systems work fine, and I'm very happy with my Straight Trak install (which required drilling some holes through the frame rails, and as I recall, a few of the bolts were fiddly to get tightened). Still, a huge improvement to my coach, and well worth time time and effort.
