With PRA's new zero-gravity trailer S.D.S.U is building next semester this is a possible much less drag with blades on trailer solution.
Just make the nose more aerodymamitic like a gyro? Not much room for tools.
Also looking for the easiest trailer I've ever seen. A Frenchman has a bump out trailer that 1/2 the center opens up so the taller gyro can be removed with blades on. He stores them on the side/edge of the roof of the trailer. He pushed the gyro in the trailer with blades attached and sticking out over the trailer roof. Then gets a latter on the inside of the trailer and remove the bolt.
He used a shuffleboard type stick on the ends of the blades sticking out 3 feet or so on both ends of the trailer and lifts one end at a time into the blade holder on the roof. It only took 5 min's for setup and teardown, or less!!!
It's in PRA 6,000+ links, videos, and pictures but cannot find it yet.
