Just wanted to give you my F150 experience. I found I was over on GVWR, RAWR. I had an Ecoboost and it towed like a dream. I think you should look at TTs first and find what fits your family then see if it fits your truck. From your signature looks like you just got a new TT. If you are wanting to stay with a 1/2 ton truck, my advice is to stick with an F150 with max payload and max tow with the Ecoboost. Others will chime in with specifics, but having spent the past 6 months looking at trucks, weighing my set up at the Cat scales, this is what I have found out.
I had a 2011 F150 SuperCrew, Ecoboost, 6.5 ft bed with 3.55 gearing.
