Hi bobsue2,

I moved your post to a better area for the question your asking about the fresh water tank on a Bighorn.

The drain, I think, is just in front of the door side tires, behind the steps.

Actually, on a 2009 BH3670, the fresh water tank drain is just behind the sewer fitting, in front of the driver's side tires. The ones on the other side are the low point drains.

The enclosed underbelly is standard. There should be three tubes sticking out, in front of the tires. The two on the door side are the low point drains for the plumbing system (should be a sticker on the outside wall near them). The single tube on the off-door side, just behind the sewer connection, is the water tank drain. Each tube should have a small brass fitting on the end, which is a valve. The "handle" is tiny, but it is a valve.

I don't think HL has changed to a screw-off cap, like some other brands have, but if there is a big white cap on the end of the tube, then unscrew it and the water will flow.

About the only thing the owner's manual is good for is starting campfires. So generic that all a RV company has to do is change the cover and they can all use the same one. It was no different with our TT.
