Here's the setup: There's a luxurious, full-size RV. It weighs 11,000 lbs, it's got a full interior (including a fridge and sink), and it's converted to run on propane. Your job is to drive it approximately 900 miles, basically untested, through the treacherous, boulder-strewn trail between Esenada and La Paz. The year is 1969, and the RV is named "Debbie," and the challenge is to finish the Baja 1000 alive and in one piece.

The man for the job was off-road legend Bill Stroppe, and this is the tale of how he turned a recreational vehicle into one fully-fledged, coulee-conquering, dirt-slinging, 400-hp off-road racing machine.
