Well, Today with everyone's suggestions and help I bought a Keystone Bullet 210RUDWE. dry weight 4060 pounds. Tongue weight is 460#. It is Aluminum construction with Glass sides. I'm happy with the deal I got, I just will be happier when I pull Vantage at at least 50 mph. That would be a feat. Vantage for those elsewhere in the world is a very long steep grade that goes from the bottom of the Columbia River basin to the top of the plateau. Thanks to those that chimed in.
