I've only done it once. Built a "fort" for the grand kids. Used Titebond II and deck screws for several laminated 2x6 post. That was at least 10 years ago and she is still standing tall. At one time the oldest grandson wanted to "remodel" the fort, when he remover the screws he said the boards were "still stuck together".

Pressure treated - so it's going to be outdoors. You need a waterproof glue.
+1 Titebond II if the wood is pretty dry or Gorilla glue (polyurethane) if the wood is a little damp, it will be messy as this glue will foam or Liquid Nails if the wood is a little damp. Good enough for Norm to use on his outdoor builds. Hard to get a thin bond though.

Thank you, The titebond was I was leaning toward.
Titebond claims that Titebond III is waterproof type 1 Ansi; and Titebond II is type 2 Ansi approved for waterproof.
Here is a description of the Ansi specs: http://www.woodworkingnetwork.com/best-p...2-adhesive Type 3 has a longer open time as I recall and that might be the deciding factor.

TBIII is supposedly water/weatherproof, but my experience is it doesn't work well if the wood is wet to start with. I'd use Ape glue, just know about those bubbles ahead of time, always clamp stuff you use it on, or it will move it to a different zip code. I do, and you can also swap wood screws for clamps It's junk wood to start with, so not likely you are building an heirloom....

PL Premium. comes in a caulk-type tube. Lasts longer than the wood.

Gorilla glue. I have used Titebond 2 but mitered joints on facia boards opened up. I tried Gorilla glue and that is all I use outside now.

I wouldn't rely on any glue (exclusively) for wood that is constantly exposed to wet, cold and heat. If it supports people or construction, I would use mechanical connections as well.

If you use Gorilla glue you are told to lightly wet the surfaces first. Apparently it improves the bonding.
