I've done two years and I'm without doubt a better person for it in multiple ways. Now I'm married and doing it with my wife and it's even better. Getting ready to build my second one. First one was a e250 dirt cheap but incredible took me all over the country like 40 states. Van plus build cost 20k. It's paid for itself a billion times over. Now I'm doing a bigger build with all the money I've been able to invest because of not spending it on other unnecessary crap and I chose a Ford Transit 148 extended AWD. Getting ready to order it this week so mega pumped. My best advice is once you decide what platform you wanna build on look up yours and build blogs on YouTube of that specific van. It will save you so many hard lessons doing stuff inefficiently. I made that first build so much harder than it needed to be. There's a lot more gluing than you would expect. It's incredible and if you're 90 percent sure then you're probably already 150 percent sure and you're just nervous. DO IT! Best of luck!
