CAT Scale results - advice needed

As far as trying to lighten the tongue weight as you asked about the only thing to do is move more cargo towards the rear of the trailer. While I am unfamiliar with your trailer do the above scale weight include water in your tank? If not you might try adding water to your tank as many times they are behind the axle and will lower your tongue weight to a degree (obviously overall weight will increase though) . It wont be lb for lb but it may help in addition to moving more cargo to the rear. Or if it was weighed with water you might try with less water as the tank may be above or forward of the axle. I personally don't travel with much water at least if where I am going I know I can fill it there

I am not weight police this is just food for thought. I would double check the rating of the oem hitch setup. The 2017 expedition brochure states max tongue weight with a WDH is 920/930 lbs. 1300 lbs is about 40% over that rating. While I personally am not opposed to going over a rating to a certain degree 40% to me personally is beyond what I would be willing to exceed any rating.
