Changing from 3.73 to 4.10 gears
Hello all, After towing our new Reflection 320MKS from Eastern Iowa to Estes Park Colorado and back, I need more power for the hills. I have a 2015 F-250 with the 6.2 Liter engine. I have 3.73 years...

What's saying you MUST stay in that gear?
As long as you aren't in 1st, you can always drop down another gear to accelerate. If you're running out of power in 1st, you probably shouldn't be where you are, OR you've got serious mechanical problems.
In the case of the OP, where he's locking out 6th AND 5th for a majority of the trip, I agree, a gear change is a good idea, and I agree, 4.30 or nothing.
The point was that once you slowed down on a steep grade that a lower rear end ratio will allow you to regain speed easier and quicker in all gears.
If you do not believe this... Then there are a lot of drag racers that have been doing it wrong.
You are a little bit off track. It's true that with a lower gear ratio a race car will pull harder in every gear than the same car with a high rear end however, this does not mean that it, or a pickup truck for that matter, with a lower speed rear gear will pull harder at every speed. So if you are towing with two similar trucks both in the say 3rd gear at 45 mph and one has a lower speed rear end, the low speed rear end one will out pull the other for a while until it shifts into 4th at say 50 mph. Now the higher speed rear end truck has the advantage.
