Just as an afterthought, you might consider buying and older low mileage Motorhome and scrap out the body. This gives you a chassis already set up for your Motorhome project. Then locate a Art Deco Cab Over and swap the cab onto the motorhome chassis. You can salvage many of the motorhome components to use on yours. Just an idea.
