How often do you go where services are more than half a days drive from the remote location in which you are traveling? How far are you from a parts store that carrys a good stock in Mitsubishi parts? My "PMCS" involved rebuilding the engine and replacing all worn components before the first trip. What is yours? Change the oil?
You do know our trucks are NOT chevys and Toyotas, right? Parts aren't available at Walmart. They're Mitsubishi Monteros pick your vintage. It took trips to three stores to find an airfilter in a reasonably sized town in Arkansas and I was certainly shocked that a transmission filter was found at all....
My list of spares will go like this for the future:
Spare airfilter IN A WATERPROOF CONTAINER!----my spare got more wet than the one in the air box....
Spare tie-rods
Computers
Power Steering Pump
MAF
TPS
IAC
Alternator
Starter
All Fluids plus 10% extra.
If I'm going to be on more rocks, I may add CV axles. But I go pretty easy on rocks, plus I hear our trucks' axles are stout.
I'm not sure what your point is...you came off as pretty full of yourself though. My favorite area to explore is Death Valley and that area of the CA/NV desert (Panamint/Amargosa/Argus ranges). So, I'm quite frequently over half day travel from a source that's going to have any replacement parts at all, with no services for several miles, no phone coverage, usually no water source, and on roads or trails inaccessible to passenger cars or recovery services.
No, changing the oil isn't really something that's on my list before every trip...that would be really wasteful and expensive. It gets changed when it's dirty. Seeing as how I replaced the frame of the truck in my garage, I'm intimately familiar with the condition of every nut, bolt, fitting, hose, line, wire, and connector from bumper to bumper. Since I had it completely disassembled, before each weekend trip I put it up in the air, take the wheels off, and go front to back, checking to make sure everything is snug and "mission capable." I do the same thing at oil changes - I use these as chances to check other things over.
Don't let your engine rebuild give you a false sense of security - you should still check things before heading out into the wilderness. And if you "replaced all worn components before your first trip," why do you feel the need to carry a spare truck with you?! We aren't in covered wagons trekking west in the 19th century. You aren't going to snap your oxen's yoke every 100 miles.
If the truck is solid enough for daily driving, it's going to be solid enough for most trail runs as well. If I'm going to be gone longer than normal, or on a more difficult trail than normal, or farther into the wilderness than normal, I always have a bug-out plan and I pack and plan accordingly. If something is questionable, I bring a spare and the tools to change it, just in case...until I find a convenient time to correct it at home.
These are reliable trucks - you make it sound like you're off-roading in a Model T. The CV's weren't mentioned because of breaking them on rocks, btw. It was more in the event of tearing a boot and dirt getting into the bearings. Once a boot is torn, I tend to carry a spare axle until it's convenient to replace the axle at home with a new one.
Though, I guess if you're wheeling in a place like Arkansas where people can't spell "Mitsubishi", let alone get parts for them - you're going to have to be a little more careful.
