Hitch setup, F150 to F350?

[PHS79]

In a couple weeks we are going on a trip from Wisconsin to the Rushmore and the Black Hills of SD. For the trip I am going to barrow my parents F350 dually diesel instead of using my F150. I started thinking about the hitch setup, mine is the Reese Dual Cam and the camper has about 1000lbs of tongue weight. Currently with my F150 I have the hitch head set on 1, which is the most tilt that the head can have, and 5 chain links on the bars.

I know that I am not going to have to transfer as much weight when using dads truck (wheel base almost 2 ft longer, much heavier motor, stiffer suspension, ect), so I was thinking about moving hitch head to 2 or maybe 3 and the same 5 links.

Does anyone have any suggestions or input?

Drop 2 links an call it done. I would not worry about it.
