Van Build First steps: Framing, Pre Wiring & Insulation | A simple "How to" guide

This is our 2nd Ram Promaster Van Build and we have learned a LOT from our first Van Conversion. We are Framing the Van differently than the first time, Running the Electrical Wiring differently from the first van build AND explaining WHY we picked Closed Cell Spray Foam Insulation VS Foam Board & Great Stuff Cans. We're Logan and Kelleen Seims: L&K SEIMS  and we hope you are here to learn from our 2020 van build mistakes (because so are we!) We've heard a lot of people worry about Closed Cell Spray Foam warping or ruining the exterior of the Van... spoiler alert! This is FALSE if done correctly! (Yay!)
