I don't know about the Wallace tru-track specifically, but in general I feel that these kind of things (tru-trackers in general) are a fantastic addition to the coach. Particularly for the leading bogie, but also for the rear. The bogies flex a surprising amount when you are turning the coach, and other forces, such as pot-holes, will cause them to flex while going down the road.
There was some discussion about straight vs curved channel tru-tracks, but I think they all do some good. I suppose the curved ones are prefered, but so long as the bearing is within the channel then I'd be okay with it.
If my beloved PO hadn't installed them I would.

Install them. At least do the mid-wheel position, as it will keep that boggie pointing forward without deflection. There has been discussion about doing only the mids, as the rear wheels are in a trailing position and stay in track. Some have split the full set and two GMCers paired on the mid wheels.

My thinking on the Tru-Track system is that grit word play heck with the
slide part and bearing.
I also have a set of rear stabilizer bars. Would the bars put too much
lateral stress on the suspension members?
Any ideas would be much appreciated.
I find as a new member that I am getting a lot of good info on this
motorhome.
I have 15+ year old Michelin tires while show very little checking and only
between the side tread area. How far would anyone drive on these old tires.
This MH has not seen salt nor parking on grass so is in very good
condition, rust wise. Just a little dated interior.
I am thinking of removing the double bunk and putting a chair of some sort.
Loose some storage but gain floor space.
In putting a laminate floor does one just cut out the carpet in the walking
area? Lifting all the cupboards and dinette is a big job.
Well that's enough cvestions for now that is. Al

15 year tires. I would drive to the nearest tire dealer that had the tire that I wanted and at the price I was willing to pay, and replace them. Even for Michelins, 15 years is aged too much. Michelin claims 10 years as an optimal life. Others say 7 years.

As for 15 year old tires I personally would even drive them anywhere. Take them off and then take them to the dealer. The cost of repairing tire damage is way more that a set of tires. There are people here that know. You do what you want.

I had a blow tire on a trailer back in 1975. I did a job on the plenum tin
wheel well. They were almost new Firestone's. Got a new one under
warranty. Al

G'day,
I have a Tru Trak system made by Tom Hampton of Grandview Motor Homes and there is sufficient clearance between the roller and track
to cope with grit.
I don't think stabilizer bars will put any stress on the suspension, however, they WILL effect the ability to level the rear end at
campsites because it hooks both sides together.
To be 100% safe I would remove the wheels and tires and bring them to a tire store to have new tires fitted.
The carpet in the Avion didn't go under the furniture.

Thanks all for the info. I will be installing the front Tru-Track and see
if they do the trick. I don't think I will remove the furniture to put in
new carpet of Laminate flooring. The tires will travel 1 mile to the tire
shop. I have a price for Firestones TransForce HT at 203.00 plus tax per
tire. Are they the correct tire? Al

Albert,
Tru-Trac, on the middle wheels, is probably the single best improvement
I've done to my suspension -- and I've done them ALL. I would not give
them up for any reason. I did not want them on the rear wheels. In the
first place, I don't think those trailing suspension arms can go anywhere
without the rest of the wheels having already been there. In the second
place, I think some compliance in the rear suspension during turns is
desirable -- more than the tires' sidewalls can safely offer.
All of the cam followers I've seen used for Tru-Trac's have sealed
bearings; grit should not be a problem -- I'm not even very conscientious
about greasing them.
I had a coach with rear stabilizer bars and never will again. Not because
of any stress but because they made it virtually impossible to level the
coach with the air bags -- when one side goes up or down, so does the
other. I've got two of them for sale if someone wants them -- no shipping
though. :-)
I'd put those wheels and 15 year old tires in the back of my truck,
carefully, and take them to the tire store. Would NOT drive the coach that
far (about a mile).
IMHO it would be foolish to remove the cabinets just to get the carpet
out. Even when I replaced all the cabinets, I did not put the new ones on
top of the carpet -- that's purely a production line time saver.

I might need some help on putting a signature on all my mail. As to the
rims, they are 16.5 with Michelin's. 875 75R/ 16.5. They towed OK from
the seller to the service garage and then home, total about 65 miles. They
have been in a garage since about 1990. Al

I currently have the transforces - its the only one Firestone makes in the 16.5 truck size. Mine are two years old with 50 miles on them. I'd make you a heck of a deal on a set already mounted if you were close enough. I have a set of Alcoas waiting. 
I'd be interested if you decide to sell the other half of that set of true tracks...

Al,
Firestone transforce are your only choice for a US made tire. I am told that there are some Chinese products, but none showed up in my last search. I was told that there are still some Coopers around but my local Cooper dealer declined to provide them.
