I'm a DIY guy also. Here is what I carry "just in case" in my 2001 for the V-8 engine, which is the little brother of your V-10.
...Spare "cop" (coil over plug)
...spare fuel filter and tool to remove ($10 bucks)
...spare injector (just to confirm when trouble shooting if "cop" or injector is bad)
Locking gas cap... Don't toss your old cap if you buy a locking gas cap. I fail smog test with locking gas cap for some reason?
Jack and tools to change spare tire. Recommend you do a practice run in your driveway first before hitting the road.
Make sure you use quality oil filter. Motorcraft and some others have what is called "silicone valve" in the filter. But many other filters do not. The silicone valve prevents oil leaking down out of filter after you shut it off. Reason is when you start it up again, the oil filter is still full of oil, so you won't do what is called a "cold" start every time you start engine.
Cooling system...I found it easier to drain system by removing lower radiator hose versus drain plug.
If the drive shaft is 2 piece be sure to check carrier bearing. Not uncommon for those to go bad. You might even have a grease zerk fitting there.
Might want to check overhead A/C gasket. To make sure it is water tight. Don't torque to tight. Lots of info on it, on this site.
Download all manuals for what you have (generator, awning, micro, etc)
If you get new wheel simulators (because my CA caps totally sucked)New ones were held on by a nut called a "coupler nut". Use ONE drop of removable lock tite. Don't do what I did, thinking if one drop is good, many drops are better. A very Big hassle getting those things off.
Had our CA 7 years now and still pleased with it. Only problem (other than normal stuff) was with an injector getting plugged up when we first got it.
Any questions, just ask
