Most of it has been sweat and my labor. Refinished cabinet doors, minor cost for sandpaper and quart of finish. Made a storage cabinet with wood I already had in the shop, couple dollars for hinges for door. Approximately $210 for a Wave 3 cat heater, $20 for a hose and some more $ for a fitting. $50 for a water pressure regulator for the toilet and some $ for a fitting. Whatever two fan covers that go on the roof cost.
I don't keep a spread sheet of what I've done and associated costs. I did it so it was worth it to me. I think if I ever analyzed what I've done and the costs I might get depressed. Part of having an RV is personal customization IMO. If you do it, enjoy it, don't overanalyze it!!
