2008 Toterhome Twins Custom Coach built on a  Freightliner Argosy Chassis 

Toterhome, sometimes also referred to as a truck sleeper, is a class C custom recreational vehicle that is built using either a medium duty (GVWR ranging from 14,001 to 26,000 pounds), or a heavy duty (GVWR from 26,001 pounds and up) van or truck chassis. Most often, they are built with small living quarters attached directly behind the truck cab, and then a standard 5th wheel hitch at the rear, allowing them to pull trailers. A more recent trend has been to build more luxurious units, with a fully enclosed body, and slide-outs to increase the living space.
