Whether or not the vehicle is garaged at night is a factor. If its garaged, considering the climate you are in and your short trips, Im not sure that much sludge under the cap is out of the ordinary. Ive seen sludge-filled caps in SC.

Hmmm.... but why isn't anybody else having this issue?
I was looking around in the FSM and saw the PCV torque is 31 in. lbfI also picked up a new PCV valve this morning, hoping it will cure my issues.
This is a surprisingly easy thing to change, I think it took me all of about 3 minutes. You pop the engine cover off, pull the hose off (use pliers to move the wire clamps), then use a 22mm deep socket to remove the valve, very easy. Put a dab of grease on the new one, 44 in-lbs tight.
My old valve was totally clogged, nothing could pass through it either way, and the check valve jiggler was frozen. I then drove the truck about 250 miles today, definitely aired out the engine. I'm optimistic this is the fix, will update after a few heat cycles. Truck seems to run a little smoother, but it could be my imagination.
If you have over 100K miles and no record of this valve being replaced, just do it. Cost is only about $8-9, and very easy to do.
Update with a photo, this is the PCV valve, right in front if the intake plenum, hose removed. The worst part is dealing with that chunk of foam, which I assume is only there for noise insulation. The valve is plastic, mine was actually barely finger tight when I removed it. I suppose you can just soak it in solvent to remove any accumulated oil lacquer, but it's so cheap IMO it's not worth it, just get a new one. I had to special-order mine, no dealers in my area had one in stock.

I downloaded the ISO in this thread:
200 Service Manual
Used that to find the procedure for testing and installing the PCV. Torque spec provided there was 44 in-lb.

I talked to my indy guy today, he is actually Toyota certified, and said they used to change them on all Tundras at 30,000 miles. He said the torque isn't important, he just snugged them down. The O-ring is the seal.
Sometimes I wonder how about these service manuals. This isn't the first time i've found discrepancies.I downloaded the ISO in this thread:

Good to know, I’ll go out and tighten it up a bit more.@Taco2Cruiser, apparently the torque spec was updated at some point. Either that or the torque spec for the US 3UR-FE is different than the torque spec for the rest of the world.
This is what the manual says as of Aug 2017 for US vehicles:
