ATF: North Trail - Location of low point drains for NorthTrail 22FBS?

The trailer has a sticker on the skirt just in front of the door showing the low point drains location. Both the dealer and I did not see anything protruding from the corrugated underbelly enclosure. Is this the correct location? And if so, are the drains supposed to protrude through the underbelly, or does an access point need to be created?

On my 21FBS the fresh water drain protrudes through the underbelly near the steps. The low point system drains are at the left rear corner of the trailer, you need to crawl under it the first time to see them.

After we got the trailer home and in the driveway, I crawled underneath and found the low point drains at the left rear corner between the skirt and frame. So it's in the same place as yours. Thanks. My water tank drain is also in the same place as yours on the 21FBS. So, the sticker was in the wring place...now, I'll need to verify the stickers for the gray and black tanks!
