    There is an older model here. It has a drain hose that runs with some other hoses. It drops water out inside the frame rail above the steer axle. Look there.

    Do you mean the crankcase breather for the engine itself, or the cab drain for the AC? Engine crankcase is left front corner of the engine. AC water drain is in a weird place. It actually comes out inside a channel near the right front cab mount and comes out a drain hole near there.

    Yes it is the cab drain for the A/C. Only one I ever saw that way.
    Not actually in the frame rail but on the engine side of it.
