The payload rating of 2013 BMW X5 (properly equipped) is 1290 lbs. From that weight you need to subtract the passenger total weight, the weight of all cargo, and 80 lbs. for a weight distributing hitch. Assuming 100 lb./passenger x 4 = 400, 80 lbs. for the hitch, and 200 lbs. of cargo, Total = 680 lbs. 1290- 680 = 610 lbs. remaining. The tongue weight of a trailer towed should not exceed that 610 lbs. Tongue weight of most TT's is 11%-14%. Using 13% as an average, the maximum towed weight would be 4700 lbs.
BTW, don't aim for anything too long, the X5 is pretty short for wheelbase.
Good advice.
Check your door sticker for your specific payload and plug in your own weight numbers for passengers and cargo (in or on the tow vehicle).
Also, take a look at your hitch receiver. It should have a weight rating of its own. It may not be rated to carry weight you need it to carry.
After you've subtracted your passenger / cargo weights from your payload, what is left is "available payload" for the hitch and tongue weight. Subtract 80 lbs for hitch weight, then take that number and divide it by .13. That will tell you the loaded trailer wieght that will put you in the ballpark where your tow vehicle is at its maximum weight capacity.
Average load of dishes, pots and pans, bedding, camping gear, BBQ, groceries, and water is 800 - 1000 lbs.
If your loaded trailer capacity comes out to be 4700 lbs, then your dry weight figure should be 3700 or below.
