There are people claiming 40mpg out of them cruising on flat land. Compared to the the 25/26 of the various smaller gas engines that's pretty impressive.
That's an apples (extremely limited outlier conditions) to oranges (common conditions) comparison. Put on a more equal basis, that difference shrinks.
They both seem to be shaping up as rather good engines so far. Personally, if an accurate use case assessment has it being run long, hard, and often for a 1/2 ton, I might lean 3.0 D-Max. Otherwise though, I'd probably lean 2.7T.
One big question is how many of the 'lot of miles' will be while pulling the trailer?

Actually both numbers are on the outlier conditions rather than what they are rated for. Consider it a best case scenario.
How many miles is a hard thing because this is such a non formed idea that it's basically throwing a number out there. Consider it to be "most" miles will have a little trailer involved.

The best available real world data disagrees...
3.0 Duramax:
2.7T:
Even under the most optimal conditions, I have seen no credible data or evidence to suggest the diesel getting anywhere near 60% better fuel economy than the 2.7T when all else is equal.
First hand 2.7T testimonial from a fellow GRM'er:

Simple facts:
39k miles
22.9 mpg average over those miles including no less than 4000 miles towing a 22ft open hauler with at least 4k lbs aboard...

Being a modern diesel I would also consider if you'd be using it on short trips or more highway. Emissions tech for diesels likes long highway miles, not short trips.
In reply to Driven5 :
But a 13% increse from 25mpg is only 3mpg. Looks like the Baby d is more than capable of that. Towing I hear they are even better.
Didn't GRM have a loaner 'burb that JG towed the project vette with and got like 25mpg average? Looking for the article now....
