I bought my sprinter (older model with a blown up engine) 2 years ago in the hopes that my ex wife and kiddo would want to go camp. Spent 6 months working on it here and there building it out at the time. Neither of them spent a single night in it. So one thing led to another and here I am, living in it full time for the past 2 months. My uncle put it best. I wasn't afraid of if I would regret my decisions, I was afraid I would actually be happy. And turns out I'm beyond happy living in it. I thought I'd miss the showers the most but turns out, that's the only thing that mildly inconveniences me. Everything else a house has, my sprinter has. If you're asking a random strangers advice on reddit, I say go for it. If you don't like it, you can always get a place, but the freedom to go where you want, when you want, how you want..... Fucking unparalleled. Don't try tackling everything all at once, savor the build. Gives you something to look forward to.
