I was lucky. I don't have a bedroom slide, so pin weight was around 2100#.
When I weighed the 3/4 ton with everything set up for the road, I was 140# under max axle weight. But that was with empty tanks. I also lightened the pin weight as much as I could by moving heavy items to the rear storage compartments, and mounting the spare tire on the rear bumper of the trailer. Since I had the same size wheels on the truck and trailer, I also left the truck spare tire at home. It was close though.
I told the DW that if she wanted to bring anything else, she had to lose the same amount of weight. It took about a week for the bruises to go down.
