I know it has been a while since you posted on this thread. I need a lightweight fifth wheel and have found a used 2010 single axle 19EX (I have seen a picture showing a dual axle set up as well). I have a F-350 diesel (2wd), so normally would be able to pull most any fifth wheel I wanted, but our favorite place to camp is Lake Conasauga, high in the Georgia mountains, and 13 miles of U.S. Forestry roads of just okay condition to get there. There are several sections of the route in that are quite steep, so I believe that I should go with a fifth wheel for the sake of traction.
Do you still have your 19EX, and if so, are you still satisfied with it? Do you think it could stand up to a relatively slow drive on 13 miles of dirt roads?
