Hello - after thinking and dreaming about this for a couple of years, and now that I am mostly retired, I purchased a 2021 Ram Promaster 3500 159 WB Extended cargo van. I am still in the design phase though I have purchased some items like 2 MaxxAir Fans, Havelock Wool, Kilmat, and APS iBoard running boards. So far, I have only installed the running boards - which required me to drill six holes in the pinch weld - so this has given me some confidence! I look forward to learning from all of you.
