The front drain is located.....
just behind the driver side front mud flap, right next to the outside skin.
If you lay on the ground with your head between the rear of the front tire and the front of the LP tank, the drain is located just to the rear of the mudflap/cockpit riser/LP Tank Bulkhead. The protrusion is the same as the rear drain.
If you remove the inside AC shroud, you can see the drain connection to the drip pan, about the middle of the cutout area, on the drivers side.
