Trailer weight vs. towing capacity

I'm just wondering if the RVing community has tried to do something about what is considered "dry weight" ? I think it would be beneficial to the manufacturer, dealers, and end consumer if that weight was for the trailer with all possiable options installed. I think It would make it easier for people to see those numbers and make simple addition of all thing caried in the trailer to find the total weight? If anything they might be lighter if the rv isn't fully optioned out.
