I’m sure this is a hot topic.
If the primary purpose is not gaining the lowest price, but gaining the best solution for the problem, who has the best product?
My coach has original bags and they definitely have to be replaced. I am leaning towards Manny Trovao’a one ton front end and reaction arm/brake kit as initial upgrades together with replacing the bags & shocks. Fuel line and tank work too.

Your decisions might be influenced a bit by what you read here. So be
forewarned. The 1 ton kit makes good economic sense, IF YOUR EXISTING HUBS
AND KNUCKLES AND ROTORS ARE WORN OUT AND IN NEED OF REPLACEMENT. If they
are not worn out, it might be less money to rebuild what you have. A couple
of mods like 80 mm calipers and drilling the hubs to allow for lubrication
zerks, are a good idea.
A big plus with the 1 ton is the 11 inch brake rotors, and ease of
replacement of the hub bearings.
The air bags? Not so clear cut. IF ORIGINAL EQUIPMENT QUALITY AIR BAGS
STILL EXISTED, no brainer. But, they don't. Lots of choices out there. Low
cost, systems like the Sully bag are great value. But if you NEED IMPROVED
BRAKING DUE TO TOWING REQUIREMENTS, there are several options. Cadillac
priced quality systems include 6 wheel disc brakes, reaction arms with
torsion bars or without, combination drum/disc Quadra bags or not,
Sensitized boosters, stainless steel brake lines, power brakes boosted by
power steering assist pumps, and several more systems. But, if you do not
tow or drive like Mario Andretti, the properly adjusted stock system will
serve you well for many miles. Pay your money, and take your choice.

"Best" depends on your requirements. All of the current air-bag replacement
systems are reliable, effective, and maintainable. There have been some
replacements in the past that were not, but those are no longer available.
Some require more pressure to achieve the same ride height, and some less.
The descriptions on JimK's site will give you an idea.
The replacements that use two bags would be my choice--but I don't care
much about pressure requirements. My coach is light, and with stock bags
I'm at maximum rear height by about 100 psi. If it was a late, heavy 260, I
would want one that works with less pressure. The two-bag replacements are
less complicated and easier to install.
I would rather spend less on the bag replacement system and more on
reaction rods and disk brakes (in that order). I look for systems that use
easily serviced parts. My stock bags are still good and they work great--no
need to replace them. But the reaction rod is a significant design
improvement that improves braking. It's on my list for next year.

Luke,
As you are running the e-mail and not the forum, you don't have a signature line to tell us what your coach is and where you are. To make the most effective recommendations, this is essential information. There are mods that are definitely better on some years and weights than on others. Some mods also have real advantages for how you expect to use the coach. For a simple example, I could not accept any suspension that left me with less usable rear travel. But that is because of how we use the coach.
So, if you fill us in, you may get better answers.
I happen to like Lenzi knuckles, Sully Bags and Applied reaction arms on OE drums, but I have a light coach and we do drive her hard a lot of the season.

You need to find out what each really does for you.
Quadra Bag is for people that want the best control at the rear.Has very
little with the bags, but how it is employed.
One ton front end is the same.
Lot of people in the know will discuss pro and con.

Carl,
The Chuck Aulgur Reaction Arm system we provided to you is the larger
caliper kit.
The ones with the smaller calipers do not give you much of a gain in
stopping.
We're in mid of completing the Newer Chuck Aulgur Reaction arm . We will be
conducting tests on a customers coach. Rick Flanagan is redesigning it and
he will not release the design till he supervises the testing.
I'm sure there will be some videos produced during testing.

Hi Carl,
How does the Chuck A reaction arm disc brake set compare what Manny offers?

Am I reading this right that you can have a bag fail and still drive with
the quad bag?
Over the years the allowable GVW has increased. Did the increase come with
stronger parts or did the engineers realize they could up the numbers with
the original desine?

We had Chuck come up from San Diego for few days and couple weekends
working with Rick Flanagan and our guys doing some severe panic tests.
Our new design is being done to cut costs and still have the performance
and dependability.
Rick Flanagan is a Professional Designer/Engineer, so when he requests that
we need to test his design, I cannot avoid it.
First test coach was Rick own coach.
Later that was the coach that was at 2 Western States Rally and took about
16 guys for test rive and they all returned with amazement in its
performance and the wheels were so hot you could not put your hand on the
rims.
We put one on my Cad 540 coach and I do tend to tail gate and can tell you
my experience having a 5,000 lbs of toad behind and the tode brake not
working.

You'll find that our kit will fit easily as RIck makes sure using his
computer and experiance to assure fit.
He did the Quadra Bag for us when Jim Bounds approached me to improve the
Harrison 4 bag system. Jim B can be demanding, so I'm glad Rick wa there to
take charge and design a unit that Jim B endorses .
We also have a 3 point Shoulder belt Kit now that Rick figured out a great
way to attach to the side wall.
Again I had to let him test it for strength.

John,
Apparently I'm the only person who can answer your question. I ran over
something that cut one of my bags on a Quardrabag system. We pulled
into a truck stop and found the problem. I closed the valve to that bag and
pumped the other bag up enough to bring the coach to ride height.
I looked at the one tire that was actually holding that corner, thought
about
the overload it was carrying and decided I wasn't going anywhere till it was
fixed. I called Tom Hampton who overnighted a new bag down to us.
It was a quick easy install and has been there ever since. JWID

Yeah, good choice. Only trust one bag and tire to get your coach out of
harms way. That is measured in feet, not miles. Murphy is always, always
present. If you give him a chance, he will get you every time.

Luke Walling wrote on Sun, 22 October 2017 15:01Hi Carl,
How does the Chuck A reaction arm disc brake set compare what Manny offers?
Sorry, I can't speak to the Manny system. All I know about it is that the arms are attached in a different place than the original system designed by Chuck Aulgur and Rick Flanagan.
I can say that the Jim K version is very well executed and, although a lot of work to install, fit very well. The machining on all the parts was spot on and it all went together without hassle.

Spot on Jim. Driving on one bag, and one tire is meant as an emergency measure only. Even if one were to inflate that one tire to the max rated PSI, it would be carrying right around 4,000# on a tire rated for 2,780#. Not a very safe proposition.

G'day,
Below you will find an email e-mail I wrote years ago which provides information regarding driving a GMC on less than four wheels.
OPERATING A GMC ON LESS THAN FOUR REAR WHEELS/TIRES
REFERENCE: GMC Motorhome Operating Manual X-7821A Page 1 - IMPORTANT INFORMATION ON VEHICLE LOADING.
http://www.bdub.net/manuals/X7821A.zip
GVWR (Gross Vehicle Weight Rating) represents the maximum permissible loaded weight of the vehicle.
26 foot GMC GVWR = 12,500 lbs
GAWR (Gross Axle Weight Rating) the maximum weight that an axle can carry.
26 foot GMC GAWR
GAWR = 4,500 lbs Front Wheels
GAWR = 8,000 lbs Rear Wheels
REFERENCE: Tire Load Range: http://gmcmotorhome.info/tires.html
Tire Load Range: The max load a tire can carry and the pressure required to carry that load.
D load range max load @ 65 PSI = 2,235 pounds
E load range tire max load @ 80 psi = 2,680 pounds
REFERENCE: Alcoa Light Truck, SUV, RV and Motorhome Wheels Fitment Guide
http://www.southwestwheel.com/pictures5/LTFitment-Screen_10-18-01.pdf
P/N: 160231
Style: Classic
Max Wheel Load Pounds: 2780
Capacity ratings as dual or single in highway service - bias-ply or radial
P/N: 160251
Style: LTS 5
Max Wheel Load Pounds: 2440
Capacity ratings as dual or single in highway service - bias-ply or radial
P/N: 161251
Style: Hot Shot
Max Wheel Load Pounds: 2780
Capacity ratings as dual or single in highway service - bias-ply or radial
COMMENTS:
The weight distribution per tire would be dependant on the how much pressure was supplied to the air bag supporting the remaining
tire. For ease of calculations we'll divide the rear GAWR of 8,000 lbs as noted above by four which results in a load per tire of
2,000 lbs. Operating the GMC with one wheel removed the load on the remaining tire would double; going from 2,000 to 4,000 lbs. This
is an overload of 1,765 pounds (~79%) on a D range tire at the maximum pressure of 65 psi and an overload of 1320 pounds (~49%) on
an E load range tire at the maximum pressure of 80 psi. If the tires are not inflated to the pressures noted in the previous
sentence the overload would be even higher.
CONCLUSION:
If you drive your GMC with less than four rear tires supporting the load you WILL be operating the GMC with OVERLOADED TIRE(S) and
OVERLOADED WHEELS!
