This would probably be better as a 2/year 24-month post, but I just updated my expense spreadsheet and wanted to share my findings.
Here we are at the "22-month" status. My operating expenses come to $50month and if you factor in the original equipment costs ($4,750) divided over 22 months ($215), it comes to $265/month expenses. In other words, I spent $5,860 over the last 22 months vs $13,200 on an apartment ($500/month rent + $100/month utilities) for 44% savings!
Another fact I like to keep in mind is that all this equipment I've purchased (the van, the solar panels, the generator, etc) is all still in working order and should continue to remain so. So if my situation changed tomorrow (say I got to work from home)I would still have a working camper van and equipment to either use or sell.
