Looking for Advice on a new Tow Vehicle

There is no Ram factory hitch. The undercount come from the factory. Both B & W and Curt I believe offer hitches to fit. You can get the picture frame adapter and use other brand hitches. The in bed plug comes with the hitch/goose neck prep. Also there is still a plug under the bumper. The mega cab has a lower payload rating as the cab adds weight. The mega cab is a short bed pick up bed and you may require a slider hitch depending on your fiver. I have owned 3 Ram diesels in the last 11 years and never had a fuel pump problem. Different model then Ford and GM. I second get the 3500 whatever you buy Ram, Ford or GM. I use the B & W 3600 in my 2014 Ram. I have not yet towed with my 2014 but I will in couple when I pick up the new fiver. My 2012 and my 2003 towed and drove excellent. I use my trucks as daily drivers.
