I don't think it's that stupid look at all the old Toyota 2 wheel drive trucks that had the built on huge campers on them they were dually ,and I still see a lot of them on the road today. To each their own, that's what makes the world go round.
If you are doing it to be different then have at it. If you are doing it to gain towing capacity don't waste your time and money. No matter what you do your max towing and payload will not change. In fact you will lose capacity due to the curb weight of the vehicle being higher. If you NEED the higher tow capacity then get a different truck
I would ask "why do you want to do this?" before I make comments based on assumptions.Just got a 2021 1500 eco diesel. Looking to see if anyone has converted to a dually or if I’m going to be the Christopher Columbus of this endeavor.
Not even close to being true... You can do many things to change max towing and payload...
What he wants to do might not increase, and could make it worse.
But the max payload and towing are based on stock truck with certain options. Period.
Once you start changing things. You affect those numbers. Good or Bad. And depending on what you change.
