These tents lend themselves to trailers.  You can mount them on a couple crossbars or directly to the trailer whichever is easier.  They have even been put on pneumatic struts and used as cargo covers.
    This is a very adaptable system.  The tent can be used on the vehicle or on the trailer.  It can even be left at home for those times only a trailer will do, like a run to the dump.
