Probably the most important thing to remember is that you are just going to be there a week. Some temporary changes like the vacuum leak, the gasoline, and maybe a little timing; and leave it at that. If you permanently relocating, different story.
My parents loved to camp, and pulled a camping trailer all over the USA, including the Rockies, in the 1950's, 1960's, until 1970 when they purchased their first used motorhome. This was before the interstate system, and there were some pretty significant grades! Dad was pretty well prepared, and he would take with him a complete set of hoses, the usual tune-up components, and a couple of extra sets of plugs. He would change the plugs after leaving high altitudes. His major concerns were tires and brakes. Generally would put on a new set of tires before leaving Missouri, and have the brakes relined. No changes to the engine at all; and the only failure I remember was a generator in Yellowstone on a Sunday morning. And no, a generator was not in his stash of spares!
Enjoy your trip!
Jon.
