Need advice for all-around truck that can tow

I thought I would be happy with a 1/2 T (White Whale I) Not enough power, probably mostly because .........gearing......

A lower rear gear and 5 speed would have done it. Hence the WWIII.........3/4T and way lower gears. They are 4.10

I also went to a lot of work to upgrade the 1500 brakes........3/4T calipers and pads, and larger rear cylinders. It DID stop a lot better, but nothing like this 3/4T and it doesn't even have rear disc

Seems to me what we REALLY need is a 440 swap into a RAM
