The dolly should come with the straps attached to the trailer. The only thing I can think of that may be an issue is the tire size vs strap length. You will have to ask them what size cars can fit their trailer by width and tire size. Years ago I hauled a duster on a my dolly and while it fit no problem on the rack when I made a sharp turn into the parking lot at the dragstrip the dolly fenders kissed the lower rocker on the duster and dented it up. Then I can't tell you how many times I have had people want to borrow mine and the tires on their rigs were just tall enough that the straps wouldn't fit over and lock in. And no matter how many tie downs you use to try to secure it to the deck they won't hold after the couple turns or bumps. I can tell you from experience, having the rig slip even one tire of the deck is no good. It's a struggle to say the least. Just questions you want to ask before you commit to the trip. How wide of a wheelbase and tire size can the dolly handle. And no, airing the tires down is not the fix. Lol. Nowadays all the cars are small.
