I'm genuinely puzzled by the oversight of moisture barriers in van insulation tutorials

Hey everyone, I've been working on my van build and keep seeing insulation methods that ignore vapor barriers completely! Just last week, a friend showed me their van where condensation had ruined the wooden frame after using foam board alone. This isn't a minor detail, it's crucial for preventing mold and rust in the long run. Why do so many guides focus on R-value but skip this essential step? I'm worried newcomers might follow advice that compromises their van's integrity. Can we share more about proper sealing techniques to avoid these pitfalls? Let's keep our builds durable and healthy for years to come!
