Pass the word... NEVER, NEVER, NEVER count the dry weight. This is what is used by salespeople to let you THINK you can tow a trailer. As soon as you drive that trailer off and start filling it up with stuff it will never be at the dry weight again.
Look at the trailer's GROSS weight rating. This is a better indicator because you hope you never fill it up with that much stuff because this is the maximum the trailer should weigh. But you must also subtract the weight of the extra stuff in order to tow the trailer, like the hitch, chains and a whole bunch of other equipment you're gonna need to tow that trailer.
Read the Gross weight, then compare it the the owner's manual of the tow vehicle (6500), then you must know how much everything else weighs.
Rest assured, a gas engine will lug as the maximum gross weights are approached. It's not about muscle. It's about many of the components of the vehicle (trans, differential, springs, shocks, drive shaft, shocks, wheels and tires, etc that can support the weight as you go up and down hills, bumpy roads and also be able to stop the load too. You may still need extra help like the trailer's brakes and a weight distribution hitch, but the dealer should have covered this with you.
Don't forget to include everything in the Jeep as you try and calculate this. Gear, passengers, pets, ANYTHING carried in the vehicle counts. This will also be the case if you upgrade your vehicle as you try and gain some "margin" for your rig combination.
Sounds like you've got a lot to learn. Learning this AFTER you've made your purchase means you are taking a chance.
