If the dry weight is already within 300 lbs of your max towing weight then you will be well over the limits after you load the trailor with all the essentials. Whatever you load into the trailor, has to be added to the dry weight and believe me it adds up quick. Chairs, food, water, drinks, propane clothes, etc....
Also the listed towing capacity of the truck does not take into account your on body weight and gas.
