I special ordered a 2012 Ford F-150, Ecoboost, Crew Cab, 4X4 with the Max Tow Package AND the Heavy Duty package. (You can't find them on lots). I had to wait 3 months for it, but it was a HOSS! It had a payload over 2000#, tow rating of 11,500. We no longer own it, but traded it in for our current vehicle. They couldn't wait to get it back and gave us almost as much for it as we paid for it. We put over 50K miles on it. It got pretty decent fuel mileage, too.
I ended up wanting a larger fifth wheel, so we now own an F350 DRW Crew Cab 6.7L diesel, but I sure do miss that F150. I was the most comfortable ride of any truck I have ever been in. It was more comfortable than DH's Cadillac.
You CAN get a 1/2 ton vehicle that can pull a pretty good size trailer (we pulled a fifth wheel), but they are few and far between.
