Renewing Trailer

Our neighbors bought a used trailer and they have quite a crew redoing the whole thing.  They put a neat green aluminum roof on it.  Now they have torn off this side and have recovered it.  Starting to put the insulation  on it now.  Also fixing part of a floor in a bathroom.  I can see the whole inside of the house so it is interesting to watch.  When they get done, it will be very nice 4 bedrooms and 2 baths.  Then they will haul away their old trailer as it is  in really poor condition.
