We were dead in the water twice in 8 years of GMotoring.
Once got bit by vapor lock; exactly after paying for entrance to Grand
Canyon South entrance.
Got JUST out of the toll booth [maybe 100 feet] and there she sat. For 2
hours. a MENACE TO TRAFFIC.
Diagnosed it fairly quickly [hot day , 90ish, high altitude, recent
fillup, and had just drove about 40 miles up from Winslow on blacktop
Park ranger was polite but urged us to call for a tow. Nothing
worthwhile within the park there.
While we waited for a tow, well over an hour, maybe closer to two, she
came alive, on the umpteenth try,......... and away we go.
The upside of this adventure was that we stopped at a ranger office to
scope out the area.
We mentioned our trials and he allowed us to park overnight there, in
the visitor welcome center lot. Premium spot with great views. Free.
Second time was in N. Alabami, on way to Rayne rally in Louisiana.
It was later in the day. Making good time. No problems.
Stopped at a Mickie D's to use the wifi to check mail, got back into
coach within 5 mins [wifi was out of order] and was met with a no start.
No nothing, NO sound, no engine music, no nuthin. Overnighted there,
good safe place. Checked with local cops to alert them.
Phoned Emery who called Mr. Erf and between them, they advised a 'get
around'.
Hot wire from the fuse panel to the foot of the steering column. To the
famous purple wire and of course, a paper clip jumper too.
SO away we went.
Had to go thru New Orleans and do the jumper trick at every stop but it
got to be second nature between me and co-pilot.
At rally, John Sharpe [how did he ever get that name] It is karma.
John correctly diagnosed the fault as a broken rack [fragile die casting
part] which sits in the column and is driven by a gear that is on the
key switch end.
Turned out that part is a common failure and we found one on the Help
board of the nearest parts store. Less than $8 AIR.
John performed a 'columnectomy ' in the parking lot of the rally.
I firmly believe that if YOU BELIEVE you can, YOU CAN.
Don't fear the coach, respect it, treat it well [ MAINTENANCE AND
PRE-FLIGHT CHECKUPS] and it won't let you down. KEEP COOL.
ALSO, great thanks to our support staff, in my case, Emery, Mr. Erf and
John Sharpe.
We have been motorhoming for 50+ years with a variety of contraptions
and the GMC thing is the BEST. Never forget it.

Jim,
This is why I carry the spares I do:
"drove an hour in one direction to a NAPA store only to be told that the replacement would take 4 days to arrive from Winnepeg."
I also note you stated "A few spare parts wouldn't hurt either."
Agreed - I carry:
Alternator - (with double pulley installed) used it once far
Starter
Water Pump
Fan clutch - used it once so far
Distributor (complete) as well as ignition module, and ignition sensor
Fuel Pump
Fuel Filter
Exhaust manifold gaskets & donuts
Thermostat
Belts
Upper and lower radiator hoses
Transmission governor & extra plastic gear
CV joint
Front Wheel Bearing and seal set
Rear Wheel Bearing and seal set
Air Bag
Many readers will say I'm nuts and the list is overkill, however, from what I've read here it is time, cost, and quality efficient!

From: James Hupy
Last Summer while doing the Cascaders Canada Cross Country Rally, I
experienced a sudden increase in gasoline consumption. Premium non ethanol
fuel approaches $6.00 a gallon in Canada, so I was wanting to find out what
was up. We were in Pocahontas Campground in the Canadian Rockies north of
Banff. Not exactly the center of the universe. My 403 mechanical fuel pump
had at some time in it's life been replaced with the wrong pump. It had a
return line fitting that is not used on the motorhome, and was blocked off
with a rubber cap and hose clamp. That fitting cracked where if exits from
the pump housing, and was spurting out gasoline every time it operated. Did
not leak when sitting still, and with a hot engine presented an extreme
fire hazard. Dwayne Jacobson and I laid in the wet leaves and mud and
removed the old pump, drove an hour in one direction to a NAPA store only
to be told that the replacement would take 4 days to arrive from Winnepeg.
I bought a hack saw, an 1/8" pipe tap and tap drill, and some JB Weld. On
the dumpster outside the NAPA store, I cut off the fitting, drilled and
tapped the hole in the housing, mixed up some JB Weld and screwed an 1/8"
pipe plug into the hole. We drove back to the campground, installed the
repaired pump, and started the engine. Leaked like a sieve. So, I unscrewed
the fitting, and Dwayne laid under the coach and scraped off the JB Weld on
the pump. I put about 5 wraps of white "teflon" type thread sealant tape on
the plug and screwed it back into the hole. No more leak. We limped into
Winnepeg and picked up 2 new mechanical fuel pumps, and 2 Carter 4070
electric pumps for back up. About $600.00 US money in Canada. Other than
some bad Sinclair gasoline no more problems the rest of the 7005 mile trip.
You can repair most anything on a GMC if you have the knowledge and tools.
A few spare parts wouldn't hurt either.

Regarding arrival of winter, George, I was just watching
the Weather Channel and they were guessing how much snow
was going to hit the Boston area this weekend. Guesses
ranged from 15 or so to 40 inches!
Getcher shovels out!
Where in NY state?
I'm originally from Chautauqua County and wife was from
Seneca Falls and we met at SUNY in Albany.

Was the Jacobs an led triggered ignition? When Chey came out with the LT-1 in the Corvette around 1992 and then the Z/28 and Firebird they used a dual led triggered unit on the front of the crankshaft and moisture would get inside and cloud up the light. They had to modify it with some sort of ventilation system. I had a 1955 Z/28 and had no problems but the early ones were a problem.

I have only been "alongside the road" twice, actually once, but read on......
Driving from Lower MO to Ft Collins during the winter, I noticed in the mirror that the coach was down on it's haunches. In other words, the compressor shelled out and the bags were down. I stumbled into a gas station and air up the system to get me to the Ramada inn. Whilst there, I bought shrader valves and never had that problem again. Bought a new compressor when I got home.
Then once down in S Padre Island, I couldn't get started, no fire. I had installed a Jacobs aftermarket ignition, remember those? Turns out, after speaking to the tech guy on the phone, they had had troubles in damp climates. So....I reinstalled the OEM ignition, took me about an hour. Never reinstalled the Jacobs.
I think that, as a newbie, you are asking the same question I asked many years ago. I can tell you that if you decided that the GMC was not for you, and bought something more "modern", that you will be sharing your adventures on some other forum, telling about being left alongside the road with your modern rig. Ask me how I know this.

Pretty impressive you got to admit.Not too,too much that stops these machines.Ask any of the dealers/vendors.Even old junkers with a tree growing through it.Still can drive around.With my Cad over all the years and now the past few with the coach.I had a couple vapor lock slow ups,but switch to the electric pump on the aux tank and she spits right back.I carry now giant open end wrenches for the bags and spare cones with 13.5" pipes and giant nuts and bolts and washers.I also have a small floor jack as well as the stock chain one.Spare belts, hoses a can of Suva with a pig tail.I need a nice little high pressure air pump,still.I also have a spare,spare tire as I was able to get 8 new tires recently.So If I do get a flat,bad one,I still have a spare,cause what wally mart is going to have one?

Nothing has ever left me stranded. I have had a few things go bad.
1. Lost 3rd gear. Drove home in 2nd. Replaced the trans about a month later with a Manny rebuilt.
2. Hole in radiator. Patched it with epoxy plumber's putty and drove about 400 miles to the Harrington, Delaware rally where several GMCer's, including Colonel Ken and Emery, helped me install a new aluminum radiator supplied by Gene Dotson. They had a "no working on coaches" rule at the site so we called it a "seminar".
3. Ignition module went. Changed it on site (Interstate 65) and continued on my way 10 or 15 minutes later.
4. Pre-emptively changed a tire on Nachez Trace that I did not like the looks of.
5. Blew a rear cylinder wheel leaving the Rayne rally. Drove 5 miles back to the Rayne rally site. Went to an auto parts store, and got a cap. I capped off the brake line. I borrowed a vacuum bleeder from Emery and bled the brakes. Then I drove about 1000 miles home. I never knew the difference, if there was any, in braking.
Maybe some day I ought to replace the wheel cylinder and hook it up again. I'm just joking. I replaced all 4 rear cylinders later that year. They were dirt cheap.
That is all I can think of.

We had a bad fuel pump. The first time it stalled, we thought it was vapor lock since it started up after sitting for the night. We got about 100 miles down the road and it did it again. We found a GMC friendly mechanic in St.Louis thanks to the blacklist. He replaced the fuel pump and all has been well since.

My one and only happened just last month on the infamous California Grapevine. During the trip south from Washington, one of the fuel gauge senders had crapped out, registerring full all the time (Open wire?). So, I thought I had one good gauge. It registerred just over half full as we hit the bottom of the grape vine, on a hot (75) January day. I turned off the A/C, and determined I'd fill up after reaching Gorman, rather than carry the additional weight of the fuel up the hill. About 1/3 of the way up the hill, typical vapor lock symtoms started up. I pulled off to the side of the road, and let it cool a bit, and noticed that now the "good" fuel gauge read less than 1/4, Bad news... Only then did we calculate that either we had either gotten about 14mpg, or it really was only about 1/4 tank left.
Now, once you start up the grapevine, there is no turning back. No turn arounds, and it's all a steep up hill ahead. After cooling a bit, we headed on up the hill, thinking that we might be in trouble. A little later, it started coughing again, but now there was no place to pull over. Finally, on it's last gasp, we managed to get it all off the pavement, except that the back corner was still sticking out about 1 foot. Trouble was, we were also about to tip over, with the verge sloping away. At 1/4 tank full, there was no way for the pickup to now reach the fuel, so we never got it started again.
After a 7 hour wait on the AAA+ tow truck (don't ask, that's a long story), we got towed to Gorman, where it started and ran fine the next morning. I then installed a new mech. fuel pump plus an electric backup, and we won't drive with any gauge lower than 3/4 full until I can drop the tanks and fix the gauges.
Winter fuel blend and high temps just don't go together well, which started our chain of events.

Beg to differ but 1967-69 Z28's had 302's I had one still kicking myself these were basically a 327 with a 283 crank and were well under rated in horsepower to make trans am rules at the time.

Yeh. And a 307 low performance. They did this by mixing the 283CID and 327CID compnents.

The tunnel port car had substantial power on the Chev, and easily went past it on the back straight, but didn't stick nearly as well and lost it back in the crookeds.
.
. A 1955 Z28?? 1967 seems about the year I remember for the Z28 302 I believe but I'm not a hardcore Chevy guy.

Yeh. And a 307 low performance. They did this by mixing the 283CID and 327CID compnents.

Interesting. They were marketed locally as '305' which may of been to put them a bit up on Ford's 302 inch engine of the day. If I did the math right, a 4 inch bore with a three inch stroke will give 301.68 C.I. in 8 cylinders, using 3.1415 for pi.
4pi=12.57 sq" time 3=37.71 CI per cylinder times 8 = 301.68 CI total.

From http://www.holisticpage.com/camaro/camaros/302.htm
"In 1967, Chevrolet was busy promoting their new pony car, the Camaro, and part of the promotional efforts included racing the Camaro in the SCCA Trans-Am series. In order to make the Camaro competitive, Chevrolet introduced the Z/28 option package which included among other things, a special 302 cubic inch small block. The engine size was a result of the SCCA's 305 cubic inch displacement limit in the Trans-Am series at the time. The 302 turned out to be one of Chevrolet's finest small block offerings, and the engine stood in stark contrast to the ever increasing size of the big blocks used in the muscle cars of the day."
