I like this build, the author added in a shelf for the trunk of a sport utility on the cheap, and it folds down to stay out of the way. Only a few things that maybe worth changing. One, you need to take the split fold down seats into account. Two, I would spread the legs out a bit more. Oh and three, I would have custom made the legs to avoid the $18 per leg cost. Oh and up (some are $30 a leg).
