Help identifying a leak or two

[DanInDenver]

Need help in identifying this leak and its source. Last weekend noticed antifreeze reservoir was low. Filled it. This weekend reservoir is empty.

Truck spends the week at the airport so no miles other than to and from airport (~20).

Had TB and WP replaced in March of this year.

What is odd is the location of of the dripping - see photos below.

Is it possibly the line going to the rear heater under the drivers seat??

Possible I have two leaks and this one isn't antifreeze but something else?
My mechanic skills are very limited as in I can replace Oil, fluids and change a tire. Any thoughts are appreciated.

The first photo show the accumulation.

Second is looking up from there. Notice drip on grey plastic connector

Third is forward from there. The dry white indicates antifreeze correct?

Update. I ran the truck for a minute, then let it sit. Came back in 20 minutes and found a small puddle.
Found a lot of dripping farther forward under the engine drivers side.

Still can't see the source. I don't see the drip from the further back position of my OP.

That red stuff looks like ATF to me. Does it stink an feel slippery like oil or does it smell sweet and feel like water?

I agree, other than the op noting coolant reservoir seems to lose fluid.

Where it's drying pinky and crusty = coolant.

Heater hose leaking on back side of engine or rear water bypass leaking?

Fixed It

First thanks to all who replied and offered their thoughts.

Looked into it again this morning.

I traced the drip up and found a small hose that was leaking. Appeared the clamp was weakening and allowing coolant to drip through.

Pulled the hose off, replaced the clamp and now no drip.

My drive is inclined. I think that when I have parked in the drive the drip made its way across the top of the engine under the manifold. Then dripped farther back as seen in my first post and pic.

The coolant at that point had lost most of its water content so it resembled ATF, that and the location was worrisome. No drips from this location now.

So far so good after a few test drives.
