Chevy or 3.5 ecoboost ford if you're staying 1/2 ton. Not a fan of Toyota. Now if we were talking mid sized trucks or compact cars, then Toyota... Not a fan of their full sized trucks.

GM RPO Codes, or General Motors “Regular Production Option” codes contain lots of valuable information about your GM vehicle. Identify your GMC or Chevrolet rear end gear ratio by the RPO Codes, usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box. (Accurate identification using the GM RPO code assumes that the rear end has not been previously modified) The prefix is usually F, G or H when referring to Axle Identification.

The problem with Toyota's monstrous size OHC 5.7 knockoff of a GM Northstar is that it has reached the peak of it's power potential without adding boost or cubic inches. Same with the Ford 5.4 dohc. Adding boost or size makes one hard to fit into the vehicle without major body design.
GM and Dodge have stuck with the pushrod engines and still have more power to be gained from a naturally aspirated engine and room left under the hood.
Ford's fix was the Eco Boost to stay up with power requirements of the competition not that Tundra was ever any real competition. I have no idea what Toyota will do to keep up power wise except to phase out 5.7 DOHC motor and go to a straight pushrod motor like they run in NASCAR. If they elect to boost the 5.7 dohc they gonna need a lot more under the hood room and a big ol hump on top of the hood to hold all that stuff. If you think they are UGLY now just wait.

If towing near capacity of the 1/2 ton, I would opt for the 3/4 ton. I can only compare my F-250 with 6.2 gas vs. the Tundra 5.7 , towing the same 28' offshore boat. Power wise the F-250 out pulled the Toyota and handled the load much better with sway and stopping included. The Tundra was a better ride with out a doubt.

I had a 2010 6.0 3/4 chevy 6 speed auto and currently have a 2015 toyota tundra 4 door and the toyota does just as well in every department except maybe comfort and does better in fuel mileage. I would go toyota, but thats just my opinion. That full size cab gives so much room its crazy. And lets be honest, you dont buy a truck for fuel mileage. So getting 15 mpg is plenty imo. But that comes after getting around 12mpg on the highway and around 10mpg while pulling out of the chevy.
