I thought we had debunked this myth earlier. I've never heard firsthand(or
even secondhand for that matter) of an actual case where a insurer denied
coverage due to a mechanical alteration of a vehicle. I suggest you review
your insurance policy(with your attorney if you're not comfortable with the
policy language) for any such verbage. It's a legal contract, your insurer
doesn't get to make these decisions after the fact. If you or your attorney
finds any such language, I would find another insurer immediately.

Gene,

Boldface the part about reading your own policy. I'm not saying there's not
an insurer out there that wouldn't try this tactic(our industry's reputation
is not completely undeserved), but I've never heard what I would consider a
reliable report of it happening.

Let's take an informal poll. Why don't we all just pull out our policies
over the next couple days, read them and report back whether or not we found
any clauses pertaining to mechanical alterations? Any companies that use
this sort of clause should also be shown in the insurance section of your
page. I'll look at my policy again tonight.

Patrick et all,
I just reviewed my policy and found no clauses or statements concerning
Mechanical alterations. Lets get real here, replacing a brake line in
not an alteration, but a replacement of an original. The same goes for
lights, window, wiper blades and so on. If you replace your brake pads
is that an alteration??

For some of
us, we get as much recreational pleasure from tinkering and making
improvements as we do from using our beloved GMC's for travel.

This is very much my point. I suspect that for a significant number of the
owners, the tinkering is very much part of the pleasure of owning the GMC.
However, if we're going to tinker, why not be sure that our tinkering is
indeed an improvement.

modifications to the GMC is what are he trade offs. Any modification from
the original design has a tradeoff. General motors did extensive testing
on
this coach and even heavily involved women in the interior design.
I contend that all of these mods do nothing more than customize the GMC to
the individual. Do some of them work, sure but at what tradeoff? Is fuel
injection better than the quadrajet? Maybe.

I would argue that the difference between customizing and improvements is
very significant. A new paint job is a customization. as is a newly chromed
bumper or even a change of taillights. Changing your brakes to improve the
60-0 stopping distance is an improvement. Tweaking your suspension to cut
down on rut wander is also an improvement. These things are clearly
measurable. Is fuel injection an improvement? Only if it clearly meets
defined standards that are agreed upon and are measurable. Otherwise, it is
as you say, a customization.

unfortunately the real world differs from what's ideal... in my opinion
anyways. While it sounds great on paper, it's my opinion that it would be
difficult
to put into practice with one's personal coach... at least mine that is.
Speaking only for myself... many mods/enhances I've done in the past were
initiated at downtime making it difficult if not impossible to run
meaningful before/after comparisons.
With reference to brakes... I'm quite satisfied with improvements, any
improvement, so whether it stops 30 feet shorter or 10 after the mod is
irrelevant to me, as long as it stops shorter, better and/or more efficient
than before. And if it doesn't, oh well.... better luck next time. I have
no
plans or desire to stress my coach to the point were a before and after
comparison is useful and/or meaningful.

I always try to keep a return option... return to pre-mod that is so if I'm
not happy I'll revert and pass on my experiences to those interested just
as
I do when I consider a mod/enhance a success.

Yes, I'm going to switch the front rears to Leigh's brakes. Not because I'm
unhappy with TSM's, but because I may be able to do better. The TSM's have
given me a taste for discs and now I'm simply exploring to get best
possible
:-)
I'm not a scratch builder and therefore rely on and appreciate the efforts
of the folks like Leigh, Cinnebar, Caspro, Rance and others I've purchased
from to search out and/or build/invent things that are good for my buggy. I
appreciate their pioneering efforts and their ultimate sharing so that I
may
have a better coach. I also rely on them do that initial testing and am
confident that they actually do make sure it is indeed an improvement
they're offereing as in a small community such as ours the word, good and
bad, certainly spreads fast.

I bet that it's unlikely that 2 people will have the same results or
comments about any one mod. Each one will favor it in his/her own way and
be
either happy or grumpy about having done it.
However... good luck on your endeavors, both on your coach and on your post
:-)

Heinz: Please excuse me for using an example of your coach and situation
without first asking if you'd like to be "outed" in this fashion. I think
that I owe you one. That said, I'm puzzled by your approach. If you know
that you will be changing the brakes, why not figure out in some kind
measurable fashion if Leigh's brakes really are an improvement over the TSM
product. If 60-0 is too stressful, why not 30-0. As a side note, I think
that most of us should know what our coach's will do when we hit the brakes
at 60 miles an hour. The horror of the 401 accident (where a fog descended
rapidly on a freeway and ended with an 80 car collision and 7 dead) is
unusual but not unique.

There really are times when a rapid stop from high speed is a necessity.
Should we not be prepared? Should we not have figured out which brake
system or modification will probably be the safest? If the TSM product
stops us as quickly as Leigh's for a lot less money, then we should know
it. However, if Leigh's braking system really is superior to the TSM or JA
system, we should know that as well. But this is not information that will
come easily without cooperation and commitment on the part of GMC owners. I
bet that more a quarter of a million dollars has be spent on brake
"improvements" in the last few years and not one of us really know which
system stops us the best under a range of conditions.

My hope is that GMC owners will come to expect this kind of information. If
they expect it, then suppliers such as Caspro, Cinnabar or Leigh Harrison
etc, will assume that it is a necessary part of selling GMC "improvements".
But it will not become a necessity until we made it one.

That's the point John - the issue of "non-OEM" equipment voiding insurance
coverage has been one of the "red herring" myths perpetrated by the "keep it
stock" crowd for years. Since I work in the insurance industry, I've done
my best to try to dispel this one. I would be very surprised if anyone
found any reference to mechanical condition of the vehicle in their auto
policy, but it's a good idea to read it anyway.

Patrick, is commercial truck insurance any different or maybe the law
is different? We have all seen troopers measuring tread depth, or
looking at brakes on a dump truck that has just hit a car. What are
they doing, just gawking like the rest of us, or just studying bent
metal to impress their sergeant? BTW, I'm not on either side of this,
but find it very intriguing...

Rick:

Are there not/were some large trucks that come with line-lock type system
for setting the brakes?? How do they pass the test??

What do you call the air system that semi tractor's have, either a pull-out
knob or a lever that you flip from side-to-side, that hisses at you when
you're stopped and with the engine running get out of the cab??

Even back in the very strict Bay State, the safety inspection included a
braking effectiveness test (The tester stepped hard on the brakes while
driving into the inspection bay. If it stopped OK and the pedal didn't go
to the floor, you passed.) And they had a fairly rigorous parking braked
test. (No "Line-Loc" valves accepted.).

Commercial auto insurance is a different animal, but AFAIK there are still
no mechanical condition exclusions in commercial auto policies. Commercial
vehicle equipment requirements are a regulatory issue(USDOT, state DOT/DMV).
As long as you're not using your GMC for hire, it's not a problem. If you
are, that's a whole different can o' bureaucratic worms.

If the oil delivery trucks that I once drove(in another life) were any
example, the hydraulic brake lock is installed aftermarket and is in
addition to the factory installed mechanical park brake. From my experience
with the oil truck, the hydraulic lock is much more dependable. We had
trucks with hydraulic and air brakes and both kinds used the same brake
lock.

Vic,
no problem getting "outed" :-)
I'm used to sitting on that proverbial limb [g]

I guess what I meant to get accross is that in my opinion there is no
standard that can be achieved unless you use some constants, such as
same/similar vehicle and same/similar conditions.

I think we all "test" to our own satisfaction. I certainly do and will
continue to. When installing something that's supposed to add "pep" I check
for it but look for an increase rather that maximum. Case in point... when I
added the 3.50 when doing the tranny last there was certainly more pep, but
how much was attributable to the 3.50 and how much to the rebuilt tranny?

Same goes with brakes. There was a definate improvement to go to TSM's and I
expect some more improvement going to 12 inchers and if I don't "feel" that
inprovement I'll be dissapointed and complain to the manufacturer.

However, my test will be limited to assuring improvement and looking for
adverse effects. Once an improvement has been comfirmed I am quite content
to assume that any emergency stopping requirement will also be improved. So
whether I can shorten the distance by X feet when "alert" for a test has
little meaning to me as in a real life situation many more factors come into
play.

And besides, I will have done all that I possibly can to improve my stopping
power, using brakes as an example.

Perhaps I'm too easy on the manufacturer, but I put quite a bit of value to
the fact that folks are using their own personal coaches as testbeds to
enable us to each make our own choices as to leave it as original or to
participate in today technology.

In many instances the burden of serious test is just too much for the
individual to undertake. I'm quite happy to take a fellow GMC'ers opinion on
whether a certain mod has made improvement on his particular coach. He/she
knows his/her coach and hence can tell. That doesn't mean I'll see the same
improvement as conditions not only can but will be varied.

Lets make the assumption that 3 coaches do a brake test at the same time on
3 tracks side by side. For it to mean anything you'd have to meassure
accurately the pressure applied to the pedal before stopping distance means
anything as no 2 of the 3 drivers will apply the brakes equally, no matter
their intentions to do so. Add to that "owner driver" and the babying effect
comes into play as well.

Until there is an independant "test vehicle" and a truly controlled
environment, including the driver, I'll continue to rely on the individials
comments coming down the line. I put much more value into that than getting
numbers from ANY manufaturer based on tests he/she conducted to sell their
product. Too much potential for bias.

And lets not forget... many of our "enhancers" are doing it for fun and/or
perhaos sheer dedication, rather than huge profits. That's not to say they
don't do it right or proper. I actually feel that the opposite is true...
that they take extra care to make sure their GMC (and therefor ours) gets
the best treatment possible.

And the icing on the cake... communication. Thanks to Patrick we have
instant sharing of information. Many suppliers know that already some are in
the process of finding out. At the same time lets not get too picky. If your
coach stops 10 feet shorter than mine do I bitch and complain to the
manufacturer... no, I'll exchange information to see where the problem lies,
perhaps just a heavier foot on the brake, as in me too reluctant to "tromp
it". But if I didn't stop shorter than before I did the mod I'd certainly
look at the manufacturer fo a solution as it'd be the same "reluctant to
tromp" putting the foot on the brake.

Forgive the ramblings, just my 2 cents

DOT requires truckers to have a minimum amount of tread on truck tires.
There is a big fine if you are caught with a smoothie, even on dullies.

It's called air brakes. The knob that you are talking about is the parking
brake. Most (all) trailers have a breaking system that sets the brakes if the
air hoses become disconnected or loose air pressure.

regarding Semi air brakes..... all commercial trucks are regularly inspected at
DOT inspection points and many times on shoulder of road. They check brakes ,
air leaks, tires . loose bolts, cracks,lug nuts, lights ,steering, log books
,load papers, load, etc. and also random drug tests. Its kinda nice to get
a free safety check but woe to those that don't pass. The parking and emergency
brakes in the air system consist of one or more axles on both tractor and trailer
having spring loaded air cans. You can drop air out of system by means of dash
control or system will automatically engage when air pressure drops to approx 90
lbs. The springs will not release till air pressure is brought up to operating
pressure. HTH
