It's internal Winnebago code to tell them exactly what specific model it is. I don't know all the code, but the 32 indicates length, and the letters after 32 are the floor plan code. My coach is a USQ40E. It is 40' long, the floorplan is 40E. I presume the U refers to the Ultimate model line. The other letters tell Winnebago something, but not me!! I suspect they tell someone in the know what chassis & perhaps engine are in the coach. The letters probably don't directly stand for anything ...to interpret all of them you probably need a code table like you can get for auto vin's that tell you exactly which factory bult it, the color, engine, transmission, rear end ratio, and many of the options that came on the vehicle.
thanks. Anyone else?
