Can't comment on what you're feeling torque wise, since I never had a 3/4 ton gasser, but if you can't get up to 65MPH on an on ramp, either something is wrong, or you're not driving it right.

Weight does a make a difference when driving and especially in the mountains. I agree that the sail effect is huge also. But there is going to be times when the lower gear ratio is going to get better mpg than higher. JMHO

It might be worth taking it to an independent mechanic with the right tools for an evaluation. I think I remember you mentioning it's a 2011. I would be all over changing air and fuel filters and a complete tune up.
Maybe check used car lots to find a similar truck and give it a test drive or maybe rent a similiarly configured truck to see how it pulls
