I have built a two piece Clothes Line Rack, installed with only 3 wing nuts, no holes, no brackets, stored easily and holds the heavy wet towels. The hardwood pole installs on the spare tire bracket.(2 wing nuts) The upper rack , is $30 worth of electrical PVC fittings, the square T-connector gives the top connection strength with only one bolt and wing nut. More detailed pictures on my "Photo Album" named "Trailer Modifications".
