With working AC, it sure is nice working in the bus. It’s hot out but not in the bus! It’s darn right chilly in here. Got a few more things done. I cut some reflectix to put in the sunny side of the bus and that helps immensely keeping the temp down. I also finished painting and then mounted the base cabinets. I placed the countertop on, still need to bolt it down. I framed a bit more out in the shower area and cut a piece of 1/2″ ply for the wall between shower and kitchen. I mounted the Water heater. I still need to add more backing for the shower area. It’s actually looking like an RV!
