There have been some recent posts about what spare parts to carry.
Here is an article I wrote some time ago:
You are driving down the Interstate in the early evening on Saturday night many miles from the nearest town. All of a sudden, your engine stalls and so you coast over to the side of the road. You turn the key but all you get is the engine cranking over without starting. What do you do now?
This happened to me on the way home from the Elkhart GMCMI Convention. I knew that I had fuel in the tank so I guessed that it was ignition. I pulled open the engine cover and checked for spark on a plug wire and had none. Then I opened the distributor cap and checked it and the rotor and they looked good. I then pulled out the module and found my spare one and installed it. Still no spark! I then removed the cover from the distributor coil. The coil was so hot that I could not touch it. Fortunately, I had a spare coil with me. I installed it and the engine started right up!
If I had not had the right spare part with me I would have had to wait for perhaps 3 or 4 hours for a tow truck and then be towed for about a hundred miles to the nearest town. Since it was a Saturday night I would have had to wait for two days until a shop opened on Monday.
What spare parts do you have in your GMC?
Here is what I have needed at least one time over the years for roadside repairs:
Black Electrical Tape
Duct tape
Fuses, switches
Wire ties
JB Weld
WD 40
Dielectric compound (grease)
Distributor cap, rotor, coil, module, pickup coil
Pin punch (to fit gear at end of distributor to replace pickup coil)
OR perhaps a complete spare Distributor with parts installed
Extra spark plug and Extra spark plug wire (to reach farthest plug)
Spare alternator (or short jumper for solenoid so Onan will keep your engine running)
Spare starter motor
Fuel filter
Extra fan belts
Fuses
Golf tee to plug broken vacuum line
Most of the time these parts should get you back on the road.
There are other parts that could be needed but you might be able to move along without them until you can get someplace where you can purchase and install them.
If you have TBI: spare injector, throttle position sensor, oxygen sensor
Radiator hose repair kit
Radiator stop leak
Front wheel bearing and seals
Short piece of vacuum hose
Exhaust manifold gaskets
Brake pad set (front & back)
Spare air bag or threaded rod to temporarily replace it
Transmission modulator
Transmission governor gear
This list is nowhere complete. I know people that carry even more parts such as fuel pump, water pump, CV Joint, brake cylinder, caliper, fan clutch, and shocks. There are also some who only carry a cell phone and a credit card! I guess that it all depends on your degree of risk or your degree of paranoia.
Of course, you will also need some tools with you to do the roadside repairs and you should know how to use them. If not, then ask another GMC owner to show you how to use the tools before your next trip.
Happy GMC motorhoming!

You have a one ton front end on your coach? I'd hate to change a stock front bearing on the road. I carry a rear set, when I replaced them I kept the best pair. I don't carry parts for the MSD injection, which may be a mistake one day
