Your Vanagon seems to have given you a lot to do yourself in just a year.
The mileage done in one year is uncommonly high. But so is the list of things "gone wrong". Having used VW Vanagon many times before, care in usage could be accountable for some of the damage. For example "hooks in the curtains" and other such itemsw. My experience with Vanagon's, even rental ones, good and reliable.
I've had a 90 VW camper since 92. Yes, all of those things can be issues. I'm on #2 rebuild of #2 engine. I sold it to a friend last year when I moved to Argentina. I'm back in the U.S. and am about to buy half of it back, the problems are worth the reward for me.
Buen Suerte.
