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.
