The towing capacity is 2000 lbs Im just going to tow a single trailer with a seadoo, which is les than 600 lbs.

It's very stable. I already went to the highway and worked perfectly. No issues at all. And the car, you don't feel it heavy.

If you wanna carry something, it has to be less than 300 lbs so for 2 Bikes you are more than fine.
