Thanks everyone for the responses.
After doing a little more digging I made a mistake on the Chevy Payload. It is actually closer to 3000 lbs. (I was looking at the wrong engine). I stopped at the Ford dealer and they could not find the EcoBoost with the max payload package anywhere within a 1500 mi of my location (I guess they are hard to find). We looked at the Super Duty and the family were not fans of the interior and look of the truck so it looks like it might be the Chevy 2500 HD. The hardest part of this whole process is dropping 45K on a truck, wow they are $$$$.
Thanks again
