You bought a big, heavy camper. Don't diminish your enjoyment by worrying about the load or trying to get by with minimum stuff.
Load your camper with stuff you want to take, then check the weight on each axle or better yet each wheel. The biggest concern is to fall short of the tire load ratings. If that is OK check out the ride. At the worst you might need to consider some suspension enhancements.
When it comes to loading the camper, most of us expect to add at least 1000#. I used to full time and even now take long trips so my load is even more. A thousand plus pounds sounds like a lot until you really look at what is involved: clothing/boots, food/drink, toiletries, towels, first aid kit, cleaning implements and materials, extension cords, tools, hardware and misc supplies, BBW grill/fuel, generator/fuel, air compressor, leveling blocks, backpacks and hiking gear, lawn chairs, bedding, hobby stuff (cameras, laptops, electronics, chargers, batteries, books...). I added a solar panel and upgraded my battery bank. That added at least another hundred pounds. I probably also have an extra hundred pounds of clothing. I leave the camper packed and ready to go with 3 seasons of clothing including jackets, raingear, lots of hats and about 30 days of underwear, socks, and T shirts, extra blankets. The extra means avoiding the laundromat for weeks on long trips. We also carry some canned goods and staples to get by when grocery stores are few and far between. We are way over the extra 1000# largely due to the generator, solar panels, and battery bank upgrade. Oops, forgot another major upgrade. We replaced the nasty original mattress with a nice, but heavy, 8" dual layer, foam mattress.
