Howdy Matt and welcome aboard! I am afraid you've come down with a severe case of aluminitis. Good for you.
Get out and camp. Things will break. Things you need will not be with you. Many things you don't need will be with you. Everything will find its appropriate place and you will learn the ballet of the Airstream galley.
Get things fixed as necessary, learn to fix as much as you can, hire competent help for what is left. Don't obsess.
Go camping some more. Upon achieving geezerhood, camp all the time.
The Forums are a great help but there is no match for experience. I did mention lots of camping didn't I?
