Hmm I spent way too much on a new camper many years ago-and way too much since- ain't going there, consciously force myself to not think about accumulated costs/time...
Though when I re-roofed the camper I did keep track of costs because I was on a budget and just wanted to know verses shop. If I were rebuilding like you are Id probably keep track just to know what I got for what I spent in comparison-say having it done.
But add ons, mods etc-things that just make it ours, I dunno.
If I want to do something & can afford it or have the time to squander on a project I just do it- no justification-has no meaning-(because it isn't justifiable), nothing would get done-. For those of us who just fiddle with stuff, just because, trying to keep track might be self defeating. At least for me-its the doing & end result. Seems all the finished projects etc in turn are rewarding in the task, enjoyed when we go out but tallied up wouldn't be.
So regardless yes-the 'price' has been worth it.
As far as must have that we added, would also be the most single 'extravagant' expense which would be solar.
