The top of the trailer slides off creating a nice big table. Doing this reveals all the stuff you have stored inside, like food, your tent and so on. You can also access that stuff through the locking back gate when the top is on. This is so handy, you can get at the stuff in the front without unpacking the whole thing, or the stuff in the back without removing the top. We told you it was built by people who love to camp, for people who love to camp.
