John I would wait if you haven't already weight it with the battery on the tongue once you have everything loaded in the trailer. The infrequently used heavy items could go to the rear under bed hatch. Most of your kitchen items will be behind the
axle and it all adds up weight wise and changes things greatly. Adding a little water to the tanks will also change it up fast.
I have a 16' that I pulled for 6 years with a Subaru (switched to something with more capacity recently) and had no problems once loaded up to get the tongue weight to 200lbs by simple moving items around & no water in the tanks. With the 16' I actually liked it/needed it at about 240lbs for a solid tow, so I kept a large tote box full of hoses,
electrical cables, jacks and plugs etc and carried it in the trailer and would just move it right forward inside the trailer when I wanted to add to the tongue weight. I didnt carry anything in the rear of the car or more than one passenger though to compensate for the fact I was over the Subaru spec on the tongue when running at 240lbs.
