I was a little worried about how, and where, it was gonna fit on the the actual Cozy Coupe. But it has long 'ol screws (that you have to have a drill to install) that go through the bottom...so IT WILL connect : ) And it's just a 'hitch' that's permanent, you can remove the trailer. Other than the drill to install, its not complicated, made the exact same way the coupe is. We haven't actually been able to get it on b/c the hubs misplaced the drill hahaha But it looks super durable, it's not stiff, meaning it does swivel and make turning easy, it's a good size (not that deep tho) and there's a hole in the bottom i'm guessing for when it rains and such if you leave it outside (not good for hauling sand) ; ) It really is a great addition! I can't wait to see him use it!!
