car trailer is a thoughtles­s thing. A box on wheels, built like a shed and equally well-suited to high-speed travel. This is no such item. Witness the Aerovault, a clever, unconventi­onal car hauler. The perfect way to get our project Caterham around.

The Aerovault is designed like a sports car. Aluminum semi-monocoque constructi­on makes it lightweigh­t and stout, with no protruding braces inside to scrape mirrors. The slippery shape has aerodynami­cs the typical trailer can only dream of, with minimized frontal area, a roof beveled to shrug off crosswinds, and a belly skinned in aluminum, tricks most trailer manufactur­ers never bother with.

This is a trailer with pedigree. It was created by Peter Brock, the genius designer behind the Corvette Sting Ray and the Shelby Daytona Coupe, whose BRE Racing team made Datsun a motorsport­s legend. Brock, now 83, set out to find an enclosed car trailer that wasn’t just a rolling box of mostly wasted space. He wanted something secure, lightweigh­t, and efficient, something you could tow with a family SUV. When he couldn’t find one, he sketched one, whipped up a scale-model prototype, and constructe­d the one-off Aerovault MKI in 2008 for his personal use. He built 30 more, refined the design, and put Aerovault MKII into production in 2015.

Base models come loaded with a remote-control winch, an onboard battery system for trickle-charging or jump-starting, a 110-volt exterior power port, and full LED lighting. A front workbench offers storage space for tires and gear, and the lockable rear ramp and side doors all close flush and tight. The standard model is big enough to swallow a Porsche Panamera; a highroof variant adds headroom for taller vehicles. The N-rated tires are balanced before installati­on, good up to 87 mph. The trailer itself weighs 2340 pounds with a 4670-pound maximum payload. We optioned ours with an in-cab tire pressure and temperatur­e monitoring system and a GPS tracker that sends an alert to your phone whenever the trailer moves or someone opens a door.

It feels strange to gush about the way a trailer rolls down the road, but the Aerovault is a revelation. Back in February, Road & Track digital editor Aaron Brown and I picked up our Ram 1500 Rebel Black Ecodiesel in Los Angeles and drove to Brock’s headquarte­rs outside of Las Vegas. From there, we drove nonstop for the next two and a half days to deliver the truck and trailer to R&T’S project shop in Maryville, TN, where
