Being new to owning a RAM 2500 personally.

I am a bit confused to the towing numbers.

I came from a Tacoma so 5th wheel, gooseneck where never an option LOL.

Below are the number I see when I use RAMS website for my truck by VIN.

I've been looking into campers and utility trailers getting ideas as to needs and wants.

If i follow the 20 percent of the gross trailer weight for tongue weight then I'm not left with much to stay at/below the 1600 lbs. (8000 lbs x 20% = 1600 lbs).

Am I going about this the right way, I'm wanting to keep this safe and gain a better understanding.

From the looks of it trailers are following a 20% rule and Ram is following a 10% rule, but looks can be
deceiving.

Thanks in advance.
