the best solution for long fishing rods is the thule castaway, mounted to the stock roof rack
i am building a cargo carrier that is hitch mounted that will carry surf rods vertically with pvc rocket launchers or with a thule or yakima ski rack. here is a pic with rods really for a passing school, but not with the rocket launcher attachment.
i am trying to get this cargo carrier finished soon and will keep the forum updated.
Trail hitch Cargo carrier
this would only work with a hitch receiver...so maybe this does not help you.
