Bob Anderson — physician, pilot, executive — is nothing if not a perfectionist.

He’s owned his fair share of recreational vehicles and disliked each of them uniquely. There was the Earth Roamer (anemic axles, in his opinion), the $350,000 Newmar land yacht (complex emissions technology) and a 25-foot (7.6-meter) Airstream trailer (lots of propane). Yet Anderson, 81, keeps buying camping rigs. And he’s hoping the next one will be his last.

This fall, he’ll take delivery of a Lightship AE.1 Cosmos, an RV as similar to an Airstream as a Tesla Roadster is to a Pontiac Firebird.
