Yeah the length is a real consideration.A neighbor used a Thule bicycle rack,attached to his Vanagon hatch to secure a 36-inch boat-tail of EMT tubing skeleton,with a Dacron cloth envelope,sewn by his wife.He doped it,ala fabric aircraft style,painted to match VW.It wasn't a trophy winner with looks,but he was happy with 4-mpg it added.The bicycle rack allowed quick on/off,and he did not use it for around-town driving.
