I put a hitch on my Miata because I wanted to take my bikes with me with simultaneous trunk access.
I got the Hard Dog Hidden Hitch which, when you remove the L-bracket making the vertical hitch into a horizontal hitch, is invisible. It’s perfect. I highly recommend it.
Camping weekend success - I managed to take two bikes, tent, sleeping bag, food, chairs, etc all in the trunk of the Miata (or on the hitch).
I am a happy camper.
