Nice choice! I hear you on that! I had a F150, after loaded up and ready to go I was right at my max,, it pulled it, but ran at the upper edge.
Stepped up to 2500HD and enjoy every trip! GM makes a much more comfortable driving truck for me, I know its personal preference but I am 5'9" and I just couldn't get comfortable in that Ford, no place to rest your arm other than out the window and the center fold down was to low!!
Now,, we have plenty of payload,I am super comfortable while going down the road and that 6.0 6 speed and the tow/haul make life that much better!! Good luck with the new truck!
