Default Holding Tank Venting on the Ole' 74

Attached are some photos. It appears that there is two vents 1"1/4 pvc. One on the roof that may generate some pressure as the forward hole is sightly larger than the aft hole and it is in-line with the airflow. The second vent is off the Bathroom Lav and exits on the upper right side of the coach.. See photos.

Hope this helps...
