I ended up with a Dodge 2500. It's actually a 1 ton with lighter springs. If you look up the parts for the 2500 & 3500, bearings, brakes, axles, U-joints, etc., they're all the same. The Tundra might be more or less rated as 3/4 but there's nothing to compare it to.
I also went with a Ram 2500, a 2015.
The Tundra's not rated as a 3/4 ton, it's rated as a 1/2 ton.
