@sourdough, I have the Megacab short bed. You may want to consider the DW factor. She may not like the extra length when it comes to maneuvering & parking. We had an ecodiesel, which my DW loved as a DD. She doesn't like our Megacab because of the extra length.
As such, I elected to put a slider hitch in the short bed. You may never need it, but it's worthy of consideration. In my case, I dimpled my brand new truck. I was stupid; just forgot to use the slider. It was an $800 mistake!
Bottom line - happy wife happy life!
