Casablanca Car

I want to purchase a small cargo trailer, for carrying camp gear, etc. You don't see them too often, but they're like a small "pod" shape, with a lid that locks. They're like the tiny enclosed cargo trailers that you sometimes see towed behind motorcycles, only they're a bit bigger for use with a car. Everything I find online is either for use with motorcycles so too small, or too huge such as horse trailer size, or for hauling ATV's & boats, or open utility trailers when I need an enclosed variety. If you could give a website or dealer name that would help alot. Thanks in advance.
