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.

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.

"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.

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.

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?

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.
