I checked with Curt and they list Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" Item # C13316 as a fit for all models of the 2017 BMW X3. But what that means for your M Sport version is that there could be additional trimming required to install the hitch. For more information on trimming please see the instructions for this hitch which I have linked for you.

I attached a picture of the underbody panel trim diagram for you to check out as well.

The Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13316 is rated for 3,500 lbs towing and 350 lbs tongue weight. If you were to use a weight distribution system, that would increase, however I'm sure you don't want to go that route with a rental trailer. You will be able to tow your 5x8 rental loaded as you stated. You will also want the Upgraded Heavy Duty ModuLite Circuit Protected Vehicle Wiring Harness with Installation Kit # 119190KIT to get your needed 4 way flat trailer lights. I also recommend the etrailer Ball Mount Kit for 2" Hitches - 7,500 lbs # 989900 to give you the 2 inch hitch ball and options for level towing height.
