Shortly after conquering the Gatekeeper and only 15 minutes into the trip, we thought our fun was over. After flexing the rear suspension over nothing in particular, TraiLex's left rear suddenly farted loudly and fell to its bumpstops. For some reason, the left rear airbag popped off its perch, ripped its air line off, and departed from the vehicle. After raising the back end up with our handy Hi-Lift jack, we discovered the air line had only come out of its fitting. No blood, no foul.
