Our unfinished off grid camp isn’t on an island but is a 4hr drive away, and biggest thing I’ve learned is to plan slow and try and do one major project a year. Live with how it is and think about projects to improve on it.
First year was a propane fridge and outdoor shower, lol
Last year was plumbing and septic which was such a huge improvement over an out house and portable shower, lol.
We also have a little one, currently 10mo old, and the number of weekend we travelled this year vs previous years is counted on one hand. Apparently kids require lots of stuff and time, it makes it harder to work on projects.
This year we’re getting it spray foam insulated, next year I hope to have more electrical wiring completed in hopes of having more than just my 1500w inverter and 50w panels.
