Watch: The Rallywagen Boys Reach Their Lowest Point

In part 4 of ECS Tuning and Jamie Orr’s trip from the top of South America to the bottom, they run into changing politics and changeless conditions, both of which threaten to derail them.

The simple pressure of sleeping (or rather failing to sleep) in a car pushes Orr to his limits, while a difficult border crossing into Bolivia while its president was in exile meant a blocked border.

But it’s not all roadblocks—literal and otherwise. Along the way, the guys run into a pickup with a homemade sign on the back welcoming them and offering help. Watch the whole trip unfold in their latest video.
