Very few people bother to install a good secretion system in their trucks. But when people start wheeling the obstacles like Chicken point/rock or else, the secretion system quickly becomes a must in a good off-road truck.

According to their press-releases, ARB is actively working on the new off-road secretion system to dispose the human waste in a nice environmentally friendly fashion. This is actually a rather complex system, in combines a sort of snorkel, some additions to the engine intake and exhaust systems, and some creative engineering of the driver's seat. It may be costly, but it allows clean negotiation of the scariest trails.
