Called the "retired truckers RV" among other identifiers, no doubt you have seen this or similar sized units in emails that have been going around the internet for a couple of years.
After receiving that email a couple of days ago, I searched the internet again to determine more details. After a post on another blog, someone was able to identify the manufacturer as Anderson Mobile Estates. The detail photos for the unit picture above can be seen at Anderson Mobile Heat Photos.
After looking at some of the units, I wonder if these units are actually designed for sleeping. Sure seems to be a lack of bedrooms. Perhaps all those sofas turn into sleeping space making it one mobile dorm room.
