Was contacted by a new owner's father who will be taking their new
coach to it's home in Raleigh, NC. He's scared to drive it as it's
all over the road. I drove it and it was going every which way.
Sitting still, there seems to be no slack in the steering wheel but
when driving it goes left and right and needs continuous corrections.
It IS dangerous as it is. My first guess is the steering box but what
do I know? May even be the mechanics of the front end.
Any suggestions?
Thanks.

Check the intermediate steering shaft down where the grease should be around the spline I think. Any small rotational movement in that shaft is drastically magnified in the steering.

Roger,
Having flown Cobra in the Army, I would think you can handle any GMC.
I'm sort of disappointed in you.
All kidding aside, I would check out all the shocks.
Chech air pressure in the tires.
See if the rear boggie pins are tight.

Roger,
I had EXACTLY the same problem when I picked up mine. I was dumb enough to drive it from New Mexico to Virginia while dealing with the stearing.
First, CHECK your tire pressures. The dealership left my front left tire at 30 psi instead of 65 psi. That made a huge difference.
I have since discovered a missing bushing in the stabilizer bar assembly. That was replaced this weekend and should also help.
There is still a bit of play in the steering box that I want to take care of as well, but that is another story.
Have someone wiggle the steering wheel and see if there is any play in the steering joint behind the grill. Mine was leaking grease everywhere but I saw no evidence of any play in the connection.
Good luck and keep us posted.

Roger,
If you had that type of problem, this ornamental would have done a
Kamikaze run into something.

If it road wanders, ie; darts back & forth, follows truck grooves, etc. Make
sure the tire pressures are correct & not too high. Jack up the front wheels
until they clear the ground. Grab the bottom of the tire when the steering
is straight ahead and pull and push it. If there is very much play, your
lower ball joints and probably the tie rod ends are in need of replacement.
If there is not much movement, try a little more toe in on alignment. All
the adjustment you can get on the top rear A arm bushings will help the
straight ahead steering also, but is no substitute for replacing the A arm
bushings as well as the sway bar links and bushings. That is all the easy
stuff. If this does not effect the steering, carefully inspect the forward
rear bogie pins and bushings. The rear wheels can and will steer the front
end of the coach. Been there, done that. Something is worn out or sadly out
of adjustment. My 78 Royale has worn out A arm bushings, I have a spare set
of A arms that I am rebuilding but it still goes very straight down the
road. They have to be very sloppy to do what you describe. If I had to guess
what to replace first, it would be the tie rod ends. It takes very little
wear in the "center of travel or straight ahead" position to equate to
wander.

Roger, all good info from knowledgeable persons above.........
for sure loose rear bogie pins can steer the front or make the coach "dog track".....the rear tire pressure issue is always up for debate but I run 50/55 in a gmc that's not loaded heavily...I have found that 65/75 in the rears on some coaches cause the tires not to "work" and just ride on top of the road surface.......last but not least be sure the steering box is centered when the front wheels are pointed straight ahead.........if the box is not centered the internal valving tries to return the pitman arm to center and causes the coach to drive like a 70s ford van......that is it pulls to one side but when correction is attempted it darts the other way....it also overheats the power steering fluid.......give me a call if needed to explain ...happy motoring,

Ken, if anything, the ride height's too low.
We talked about that and I showed him where to measure and will get
him the measurements soon.

REAR ride height too low should add caster to the front which would makes it steer straighter. Front ride height too low will subtract caster and make it steer worse.
The first two things to check are tire pressures and ride height.
Fill the tires based on weighing the coach. If you do not know the weight on each wheel then start at 60 PSI rear and 65 PSI on the front on a 26 foot coach.
After that look at the slip joint on the steering shaft for play.
The next item to look at is the idler arm.
Then comes tie rod ends, ball joints, and finally the steering box.
