V10 or 7.3 power vs tundra 5.7

So I've known for a long time that I'm riding heavy. I'm now in a better position to try and correct this. I currently have an 08 tundra 5.7 pullin a Dutchman rubicon 1905TH. (19' box, 25' tounge to bumper) Factory weight just around 5800 lbs so some where around 7-8k lbs. (Our toys are 2 bikes or 2 kayaks, no atvs). Factory tounge weight of 810lbs? So realistically actual tounge weight of 1k. We live in denver and our trips consist of just on the other side of the Eisenhower with a few 3-4 hr extended weekend trips into the mountains.
I'm considering an early 2000s v10 or 7.3 for their durability and longevity. But after looking in to the the power on the v10 and 7.3, they are not that much better and I would be dropping from a 6speed to a 4.
My tundra pulls the trailer ok up the the "Ike challenge course". Most of it I put it into 2nd gear, hold 4-4.2k rpm which yields 45mph.
How would the v10 or 7.3 compare in performance.
Keep in mind, I know the truck handling and suspension will be better in a 250/350 I'm more concerned with pulling.

Here is how the math works out for you:

You're going to be right at 300HP with your Tundra at 7 to 8K foot mark.

Depending on what year of V10 you get you're going to be down to about 225HP so you're going to be down about 75 HP from the Tundra you have now. THAT IS A BUNCH!

A turbo diesel does not drop hardly any HP at altitude so we can just talk about what is from the factory. 210 to 275 HP.

As you can see the Tundra still puts out more HP then any engine you are considering from the factory.

One thing that is good about turbo diesels is you can turn them up with a tuner. The 7.3 is a great engine to tune because from the factory they are tuned very conservatively. With a 50 to 75 HP tune the 7.3 will pull up Ike faster than your Tundra. :)
