By 1951 M-System stopped building the so-called 'coach-style' and converted over to the 'caravan-style' body as shown in the 1954 model with optional jalousie windows. (The coach-style trailers were the
ones with rounded corners and rounded roofs. Caravan-style trailers had flat sides and flat roofs.) The bathroom in this model was very small, but a definete improvement over the 1949 bathrooms! Note the built-in
dinette in the kitchen!
