Well, a call to the factory will provide information about whether or not it has a drain. Surely it should have????
As things stand, and if there is no fix, I would make a shallow tray out of aluminium with a drain tube down in the corner between the bulkhead and transmission tunnel, and through a hole in the floorboards. Probably one each side. This idea would be a fiddle but would work.
