Just created a van rack to carry my cat. I wanted it to be no more hassle than a trailer and allow me to load/unload without assistance. Cost $50 for the ladder rack off Craig's list and $25 for wood, hardware, etc. The dolly is essential--see photos. Drives very nice down the freeway. Not shown are the mast cradles--the stick hangs over each bumper about 5 feet.
