For pickups, it's hard to beat the new F-150 with the Eco-boost engine. I don't own one myself, but 2 of my friends have them (one guy is a Ford master tech) and they love the way they drive and tow. Torque that rivals the diesels, 18-19 mpg back and forth to work and even better highway mpg.
Late 2013 (2014 models) GM is changing the pickups and suburbans, plus word is the new engine will have close to 400 hp. I'm waiting.
Also, late 2013 (2014 model) the Ford Expedition is scheduled for a facelift, with the possibility of the Eco-boost engine available in it too. I'm waiting.
If you're shopping used, it's hard to beat the '07-current Tahoe/Suburban/ 1/2 ton GM trucks. I have an '07 Suburban 5.3 liter and it's a good driver. Gets 17-18 mpg highway solo, 13.5 mpg towing my prostar on the highway, but only 10 mpg towing the X-star. Not a ton of power but it gets the job done....for now
