||As you may have seen in my previous post, I am in the process of converting a GMC RTS 40' transit bus into the mother of all RVs.
Just wondering if any of you good people could refer me to some good info on the design of mechanical systems such as plumbing and electrical. I am especially interest in inovation, and inventive ideas you may have. I am thinking of having graywater and blackwater tanks welded and custom fit to spaces under the bus. It would seem to me that steel would lend itself well to attaching fittings. Am I right? What about freezing? Are there ways to maybe route hot water lines from the engine around the tanks to prevent freezing in the winter? I will use my bus year around, and am also thinking about the best way to insulate the floor. Is this done best by laying insulation and plywood over on the inside of the bus? Or maybe packing fiberglass under the bus and maybe installing galvanized sheet metal over it? Wondering...when installing water lines, can I use plastic pipes, or do I need to solder copper lines? Any input about the above issues would be appreciated. Thanks!
