Despite the title “Living In A Garbage Truck [1]” (link via L. M. Orchard [2]), it's not—it's a Unicat [3] (a VXL 16HD [4] to be exact), a highly mobile home on wheels (whose gas consumption is measured in “gallons per mile”) that has a bit more oomph than your traditional Winnegago [5] (if you are viewing the pictures on the garbage truck page [6] and wondering where the windows are in the exterior shots—the top folds down when driving).
I especially like the EX70-HD / MAN TGA 6x6 [7], which includes a small four-wheeled bike stored in the back of the vehicle.
