I think barter stands should be moveable. in read life they are...
so my idea is that if the stand is empty, you would get a right click option to collapse. it then collapses and changes graphics, but now can be picked up over your head like a chest. to set it up again, you must put it back onto the ground, and right click it again to set it up. you should be able to store a barter stand in a wagon for example. that way you can live out of a wagon, stop outside peoples plots and put up a barter stand go to sleep and maybe have some stuff sold when you wake up.
