My parents retired and moved to Palm Springs Ca back in the early 90's. Dad passed on in 2009 and Mom in 2011, but they lived in an over 55 retirement community that had manufactured homes, Upscale trailer houses, My parents had washer and dryer outside on a covered back patio and an electric stove/oven outside as well. Not all, but most trailers did the same thing. I asked why and it was because they did not want the extra heat coming from the dryer and oven into the house, There was still a cook stove in the house but my mom only used the stove top burners and normally used the outside stove oven when baking pies, bread etc. Kept the AC bills lower was the main reason that many do that and probably still do.
