Guess an 8.5 x 16 would work better.

The serpent trailers look pretty nice but with basically the same footprint I feel like I should get a trailer that I can use for my other toys as well. And they're about as much as a larger solid sidewall trailer.
Still not sure how I would tie down the front or get out of the car. Cutting in another door is a good idea.
