Right now I'm on stock gears with the 6 speed manual v6 and while it moves i'd like the power back and to actually be able to use 6th gear on the highway
4.88s would be perfect for your application. I have a 4 cyl so I didn't need to worry about a larger carrier - so I can't help you there. Do not consider 4.10s as mentioned below.

The alternative, is to leave the gears where they are. You mention struggling at 60 mph, but not getting to 60. Perhaps it would be sufficient to leave it in 4th gear while towing? 4th gear is 28% lower ratio than 5th on your A750 transmission. Leaving it in 4th would be close to running 4.88 axle.
This sounds all bad. First, please show me how 37" tires are only 7% larger than stock. 4.10s are barely going to make a difference pushing those 37s - you are going to need 4.88s to really get your power back. And with that large of a tire, your RPMs on the highway will still be decent so dont worry about that.
It is not a good idea to just leave it in a lower gear, you need to MAKE all of your gears lower. Think about first gear - this can be the most important at times and the only way to lower this (in your situation) is to regear the diffs. Simply put: your truck has 6 speeds, it will perform much better when you regear so you can actually use those 6 speeds. Trust me, I know from experience, and I'm a doctor
edit: i think knucklehead's response was to the original post over a year ago, not to the most recent post question. So excuse me for treating you like you dont know what the hell you're talking about
