We are leaning towards setting up a van and I have a few questions. We currently have a Gx390 4gpm cold water with 275gal tote, a twin pump roof cleaning setup with a 65 gal tank, SC, and other odds and ends. Also we do mostly residential for now....1. Has anyone tried sealing off the cab? 2. What type of liner would you put on the flooring? Make a skid or mount everything directly to the floor? Venting or opening the doors? What are your biggest likes and dislikes of having a van setup?
