See what you started....
With a 2500 you need no suspension 'up grades' or heavy duty anything.
With the modern petrol power plants, diesel is also not 'needed'.
More important...a capable WD hitch with sway control correctly set-up. Do NOT depend on the AS dealer to do it right. They don't often offer much of a choice on hitches. Do the research.
Disclaimer...we use a Hensley Arrow. 15 Seasons SFSG👍
Stream happy & good luck.
