Not to be "that guy" but I'll share what I ran into with my little trailer, smaller than yours.... is payload capacity of the 1500 truck.
My ram can only carry 1200 lbs, which sounds like a lot but is hardly anything. 500 lbs gone right away for the trailer tongue. another 400 lbs is gone with my dog and I in the cab. That's 1200-900 and the bed is still empty. Generators, gas can, some firewood, extra water jugs, barbeque, before I knew it I was out of payload, and still have over 6000 lbs towing capacity remaining (truck rated for 10000 lbs.)
This hasn't stopped or even discouraged me from towing... i know the truck can haul a lot more than the lawyers rate it for, but it still lingers in the back of my mind.
Just something to think about.
