Well we did it- moved to a dually a couple of months ago. We were very happy with our f350 srw EXCEPT when we were in strong wind conditions. Even though my DH made it work, I knew the extra stress under those conditions was always present and that's what this rving lifestyle is NOT supposed to be about. So- with the end of the model year specials and a great relationship with our salesman, we moved to a 2016 f350 dually. Already have the airlift system installed, the bacflap tonneau cover and will upgrade the fuel tank soon to a titan. Have only towed 200 miles when we brought the rig home for the winter so not enough to tell much difference. We will be embarking on a 1500 mile adventure in a couple of weeks (Havasu State Park-here we come) and are excited to feel the difference. Santa was very good to the Haddocks this year!
