Are you talking hauling homebrew from there to here .... like for the shindig ? or haul it back from here ? I think a major consideration is keeping the trailer not higher than the trunk height... that should really help on air flow...actually,,,, if you tucked your trailer up close enough it might just make the car faster,, but damn it would make backing the trailer a nightmare.... That site Paul pointed out showed me what I needed to know to make my own...
