For what it's worth....
In 2010 I bought my first RV, a 99 PaceArrow, and 3 weeks later left on a 6 week, 6000 mile odyssey to the west coast.
So your level of crazy isn't that far out of reality.
We lost 3 tires and an awning on that trip...
Check the date codes on your tires, if over 7 years, replace them. Seriously consider a $300 TPMS, such as from TST, to warn you ahead of time of tire problems.
Your drivetrain, engine, trans, brakes, if they work today they will probably work when you get home.
The house stuff, you can live without should you need to, still better than a tent.
Go fer it.
