Given the numbers - it looks like you have a usable payload of 1,600 pounds and rear axle and tire capacity of 2,540 pounds.
This camper has a dry pin weight that is already right at your payload capacity (Dry Hitch Weight: 1,910 lbs. vs. Your Payload: 1,957 lbs.) and over your actual weighed payload capacity (1,600 pounds). Your real world pin weights are going to push you significantly over GVWR and put your right up against your RAWR.
I wouldn't do it. I wouldn't like like to be that far over GVWR and that close on RAWR- but I'm the wrong guy to ask. Hopefully someone else chimes in.
