So I am extremely picky about steering and suspension, too much time pretending to be a race car driver I guess.
My coach drives straight as an arrow, very nice and predictable.
That is until you go into a turn, like a cloverleaf, then it feels like the rear wants to come around on me. I feel like it should be better.
I've checked the ride height, it's within spec.
I've checked the front and rear alignment, also within spec.
Checked the bogie play, and it seems to be within spec, but spec seemed pretty loose to me
Shocks are good.
So for those of you that can feel such things, are these machines naturally loose?
Or do I have some rear suspension work to do?

Front wheel drive. Gotta keep the power on when slightly before the apex
until well past it. Leading /trailing rear suspension doesn't help a bit,
either. Kinda the nature of the beast, I think at least. Vehicle sets the
cornering limits here, not the driver. Never tried power braking one
through a bend. Just my impressions. Most of my racing has been with
dragsters and solid axle go carts. Nowhere near the same as a GMC.

Keith,
My suspension is off, so my statement is just something to think about. Plus i know you have modified your air suspension a little bit.
I have found that setting the ride height, then locking out the airbags gives me a much better turning feeling. When I leave the system in Travel mode, I feel the back end tends to roll and tip too much, so I usually switch my switch to travel. Then after it found it's place, I go outside and hit the shut off valves, then go in and switch back to "hold". I have tried driving it in "travel" with a working air system a few times, and it just feels loose driving.

Keith,
You'd probably feel an immediate improvement simply by installing
"True-Tracks" on the center suspension arms. Eliminating the "one-handled
wheelbarrow" effect there is probably the best thing I did to my suspension
in 18 years.

My ride height controller doesn't adjust nearly as much as the stock one, it's basically off once it's happy with the height.
I have thought about truetracks, seems like a good thing for those forward arms, maybe I'll invest in a pair, or make my own.
Apply power into the turn, that should get a good squeal from the passenger seat, she's pretty squeaky as it is :D
Might have to try that tho

Or do I have some rear suspension work to do? IIRC, it can act like that if all of the weight of the vehicle is on diagonal axles, like driver side front and passenger side rear, or vice versa. Weigh all four corners and see how much weight is on each axle.
If the ride height is correct all the way around, and it would be too much work to get it weighed, the difference in airbag pressure from one side to the other might tell you something.

I had the ocassion to install a one ton front end, steering box, lower
steering shaft with all new components, all links and bushings on the big
front sway bar were compothane, new hydraulic steering damper, Quadra bag
rear suspension with 6 wheel disc brakes, all new KYB gas adjust shocks,
and rebuilt rear bogie pins and bushings. About as close to new as I am
likely to come with a GMC. The coach was close to empty of spare parts,
dishes, bedding, etc. No water in the potable tank, and no waste water
either. I drove it about 100 miles home for the owner. On highway 20 from
Corvallis, Or. to the coast. Good paved 2 lane with lots of 25 mph curves.
I started out at a leisurely pace until the bushings loosened up a bit and
things shook themselves into place. Then I upped the pace by stages until I
was pushing it a bit. Damn thing did quite well for a 40 year old
motorhome. Wife following in a Toyota Camry had a hard time keeping up. No
race car to be sure, but nothing evil either.
I have driven my coach over 40,000 miles. Stock hubs and knuckles but
rebuilt and tight. One hand on the wheel most of the time except in gusty
cross winds. It is looser in the joints than it should be, but not worn
out, either.
I have worked on coaches that had broken lower control arms and no
bushing rubber left as well as broken upper and lower ball joints with the
driver commenting that the coach handled and steered "just fine". For what
it's worth.

Mine tends to do the same thing. Feels kind of weird going into a turn but drives nice and straight on the open road. I have new bushings, bearings (Lenzi), ball joints, steering box, stabilizer, etc. in front, new bearings, shocks, sway bar reaction arms (Chuck Aulgur system from Jim K), and brand new Quadrabag system in the rear. All six wheels are within < 200 lbs of each other, or were when I had it weighed at the GMCMI in Pueblo some years back.
I have only driven it about 250 miles since I installed the quad bags and I DID notice a bit more stability in the rear end. We are leaving Thursday evening on a thousand mile round trip to the North Rim of the Grand Canyon with a few detours on the way home, where I can really get a good feel for the handling characteristics of the Quadrabag system. Hopefully it is a little better, but like Jim H says, I think it may just be the nature of the beast (or at least it's design).

The height controller has a built in delay so I'm sure it will not effect
your problem.
You might want to see if a rear stabilizer bar might help or a Quadra Bag
system.
You might confer with Bob Dunahugh as he seems to know about the handling.

Wow thats pushing it pretty hard!
It does look like the rear does come around on those hard turns, and really with that much mass in the back it's probably inevitable.
I know my minivan could be made to kick out it's rear just due to the momentum of the back end.
Maybe I need to take the GMC out to a parking lot this winter and do some stability testing...

Keith,
I reckon you need to drive some GMC's other than you own if you have not done so. I found that they all seem to handle a bit
differently. For example Kerry Pinkerton thought the Kingsley he sold me drove great, I didn't think so when compared to Double
Trouble (equipped with all rebuilt front end and steering parts. I R&R'd the steering box, relay lever, and idler arm with units
from Dave Lenzi. Dave advised that the relay lever was REALLY bad.

Keith,
I'm a little late on this discussion. But, here's my opinion.
You should have NO camber on the rear wheels. f there is any
camber at ride height, then the toe will change with any deviation
in ride height. Obviously, when you lean into a turn, the outside
of the coach goes down and the inside goes up. All four rear
wheels are now off of straight ahead. Two are towed in and two
are towed out. This can't be good. Just my honest opinion.

If we have a normal winter(hoping another mild one though!) We could hold a GMC Rally out on the lake and Do some ice racing. Have seen one GMC out on I think Forest Lake for a snowmobile event.
just have to have a tractor handy to get them off of the lake.

Oh Man Ice racing motorhomes!
Definitly need to run chains, and I have Posi, so that could be interesting, it will go straight anyway.
I think anything less than 3 feet of ice and I'll watch from a distance.
Camber, I really need to check my rear camber and bogie pin play.
Now to just find a flat spot to do that.
I have driven a couple of other coaches, one was an empty transmode that was a very low mileage city vehicle, extremely well maintained, it still had the original boot on the steering CV joint. That thing felt like a race car, but I didn't take many hard corners with it, so I don't know how it felt oversteer wise.
The oversteer issue is finally percolating to the top of my todo list as I fix the more pressing issues, more testing / analysis is definitely needed

My coach had some slop in the front end when I bought it - tightening up the steering box and replacing a very bad relay arm cured most of it, but I always felt like the back end had a mind of its own, and it tended to be a handful on interstates with pronounced truck ruts. And when I dropped the rear wheels off the edge of the road (happened when the steering was loose) it was an "interesting event" to steer back onto the road... the rear end would delay re-entry onto the road until it suddenly sling-shotted hard to the left.
A set of the Straight-Track devices on the middle wheels fixed all that. Really changed the way the coach handles and feels, and it no longer wants to chase truck ruts, and driving back onto the road is a non-event. They're a little fiddly to install, but well worth the time and money, IMHO.
FWIW, my coach has three anti-sway bars, and goes around corners about as flat as anything this big is ever going to... the main cornering limitation is primarily the upper cabinets spontaneously emptying.

I'm becoming convinced that true track / straight tracks are the way to go. That whole forward suspension arm is nice from a packaging perspective, but a nightmare from a suspension perspective.
How well does your coach level with all that anti sway hardware?
And LOL at the upper cabinets spontaneously emptying, pretty funny.

My 23' levels beautifully - drives well also. I attribute both to the front sway bar the PO had Sirum install - it's big as my wrist. I believe it's greatly responsible for the ease of leveling.

Keith,
BAck when Caspro supplied the front and rear stabilizer bars, I put them on.
I could not level it when I went camping as they were too rigid.
We have a milder stabilizer kit that allow you to adjust when camping.

I have found that with the Caspro rear stabilizer bars, what Jim K. says is
true. No torsion in those monsters. When you lift one side, the whole
coach comes along. They do, however, settle the handling down if you can
put up with the harshness of the ride.
