Want to feel really good about the old coach?

As I write this, there are more than a few newer class As with Cummins engines dead on the road.

What is the problem? A non-critical part has failed and they cannot be driven.

What has failed? A level sensor on the DEF (Diesel Exhaust Fluid) tanks has told the ECU that it can't regenerate the exhaust catalyst, so it can't
run at any power over idle.

Why not just replace it?? Because there is a parts shortage (stop smiling Jim) and Cummins does not even have a current plan to rescue those that are
shut down.

One of those I know of (from that forum only) is a 200+K$us coach that is just over a year old. The owners are full timers and are currently stuck
someplace that they don't want to be.....

The FMCA magazine lists the current recalls - it always surprises me how many there are on very new, high dollar coaches. At this point, every single
problem a GMC could experience has happened and people have figured out what went wrong and how best to fix it. Also at this point, it's all about
the community and not the company.

Yes, and I will NEVER have $200K into my coach no matter WHAT I do to it!

Thanks for sharing Matt. I've ranted before about the value in these coaches and the community that supports them. Your anecdote just reminds us that
in spite of the "attitude adjustment" required to drive a 40 year old coach,it's a sound choice.

John, I wish you could just ride over here and take the hex off the quadrajet on my Firebird. Non-E and fresh rebuild from Jegs, I expected it to work
as nicely as the one on the GMC but cannot get it to run more than a few seconds without feeding it with the accelerator pump. Very frustrating carbs
when they don't work and one of the best when they do.

Terry,

I had a lot of success with an Edelbrock Performer 625 4 barrel on my 83
350ci Chevy. Adjusted once it was installed on the motor and never touched
it again.

Todd, any suggestions on how to remove those stripes off the nose of my 78
Royale? Heat gun, razor blades, abrasive wheel, plastic burnishing tool?

Jim,

It really depends upon the condition of the stripe. If they are still soft
I have had the best success with the Astro eraser tool and wheels. I tried
to paste a link here but could not get a small clean one. Google" Astro
eraser wheel" . I found a kit for $118 with the tool and 12 discs. The tool
is specifically designed for the eraser wheel and it is much easier on your
hands and arms than trying to hold a bulky drill. On the SMC you will need
to be especially careful as it will not shed heat nearly as fast as the
aluminum and excess heat will pull the paint off the SMC. On all substrates
I run the tool at super low rpm (it has a speed adjustment screw) and high
pressure. Far less heat is imparted to the substrate by pushing hard on
the wheel at lower rpm than light pressure at high rpm. Start at the edge
of the stripe and work your way along the new edge which is created as the
decal comes off. Stop and check heat frequently until you have an idea of
how fast you can go without overheating. If the panel feels hot to the
touch it's too hot. Warm is ok. If in doubt, work several non adjacent
areas in a sequence to allow cooling. Slow is forgiving. You can spin fast
and push hard on metals but be very careful on plastics and composites.
Learned that on a Saturn door. Once the vinyl is removed if the adhesive
did not come with it, lacquer thinner or adhesive remover will pull the
adhesive. Use lots of clean soft white cloth towels like the ones they sell
at Costco. Be prepared for a "ghost" stripe after removal as the paint
which was covered with the stripe will have less fade than the surrounding
paint.

A razor blade will also work but is far trickier(and harder on the fingers)
to use than an eraser wheel. I would not recommend using a razor blade in a
holder because you lose the dexterity and feel to allow the blade to follow
the surface under the decal without gouging the panel.
