Are you a member of the moose or is this a lodge near you?
They typically have RV spots and trailer storage. I keep a couple of mine at the Moose lodge, plus you can get a good lunch and cheap drinks.
Back to topic, I too have owned a Trailex or two in the past. They are a big Erector Set, simple, lightweight and easy to move around.
But for the same reasons listed above, I have moved to Featherlite trailers. That being said, there is one sitting not far from me, but I have not been able catch the owner yet, and if cheap enough or the right trade, I will grab it. One positive thing about the open bottom is that you can work on the bottom of your car.
