You need to get the details of your tow vehicle---look up its tow rating and cargo capacity.
You will probably add about 1500 lb to the trailer, over the UVW. So say 7000 for a generous margin. you can cut that down if you travel really light. The tongue weight of the trailer should be 10-15% of the loaded trailer weight--so 700 to 1000 lb. That becomes part of the cargo of your tow vehicle. Then you must have enough cargo capacity left for people & their stuff. Do the math and see if you have enough cargo capacity.
You will definitely need some sway control, so include that in your hitch plans.
