Fellas, Need some help with this one. Saw an enclosed trailer at the Louisville, KY. Expo 2002 in July. It had a changing room and restroom in the very front of it. Can't find my literature from the show. Does anybody know who manufactured this trailer or who displayed it? Any help on this would be greatly appreciated. As all LCO's know, when we are out working there is no place appropriate to relieve ourselves. This seemed like a really neat idea to me.
