Question about towing capacity for a 2019 dodge Durango rt

Where is the fresh water tank? If in front of the axle, you may have to travel with almost no water. Water is 8.3 lb/gal.

It is very, very easy for a 530 lb dry hitch weight to turn into 700-800 lb when loaded, maybe even more depending on how you load. Add 90-100 lbs for the wd hitch. And it really should be a wd/ sway control hitch, like the Equal-i-zer. Or better yet, a Hensley or Pro Pride. Personally I would not want to tow a trailer that long and heavy with such a short wheelbase.
