The challenge is finding the stuff inside an Airstream and then gaining enough access to work on it. I have watched them be built and was there every day when our Classic was built. All the wiring goes inside the walls before the inner skin goes on. Then all the plumbing and furnace duct work goes in before the cabinetry.
Accessing the water pump and water filter can create a quick refresher course for one's Navy vocabulary.....
There have been a few instances where I have wished for an etch-a-sketch moment to clear the cabinets to see what those installers did!
Enjoy the experience. There are lots of folks on this forum that "have been there and done that" that can provide assistance based upon their experiences.
