Maybe we should start writing to RVIA and getting them to make the manufacturers post only gvwr and carrying capacity with no tongue weight in their brochures instead of the bogus "dry weight and tongue weight" that they advertise now. They seem to be open to rational ideas as they have mandated tires that have a safety margin and now all lengths have to be real instead of some imaginary number. Perfect example of that is in my experience. Had a Forest River Mini Lite 2305 that was just over 25' bumper to hitch. My Keystone Cougar 22RBS is just shy of 27' overall. Go figure how that was calculated!
Maybe making buyers subtract the carrying capability will help with good decisions. The current method gives an initial idea of much lighter weight than is true. Will my Subaru pull this 29' trailer seems to be asked way too often.
