You're losing fluid out of a closed system and have a known leak from a yet to be determined location. Based on the unknown age of the various hoses, you could start by replacing those and see if that addresses the issue. If not, you've still accomplished solid PM and removed the hoses as a future failure point. Left as is, should the current leak fail catastrophically and overheat your engine it could cost you an even larger repair.

For the OP.
The employment of a coolant recovery tank is the norm when a fully sealed system (expansion tank) cannot be used, the 80 uses the coolant recovey version.
The objective is that regardless of which system is used, all air is removed from the circulating coolant, this allows more efficient cooling. When all is working well, you will not need to add coolant from one year to the next.
Any leak will allow air into the system, and given the known weakness of the head gasket you should address this without delay......oh, and change your mechanic.

on my 3FE, I bypassed the TB lines and stopped loosing coolant...
My bottle just cracked right down the weld seam. Great timing cause i had picked up a spare i got from a mud member part out. Whew! I might try plastic welding it back together as a spare, but might go to something more sturdy as well(aluminum).

As this is not a pressure vessel, a crack would be a result of impact, rough handling or a manufacturing problem, certainly not seen as a regular problem AFAIK?

Yeah, or drying out. It had popped off its mount one time and worn a hole in it so i plastic welded it back together on the trail with a lighter and zip ties as welding rod. I thought thst had finally given up but it was the factory seam. I don’t know why it failed, but its not my first plastic overflow bottle failure in my years. Usually its from an impact or something rubbing through it due to owner neglect.
Dude, neither had i! But i had just handled the translucent zip ties in my tool bag and then felt the overflow bottle was very similar plastic. I used the blue part of the flame until the bottle got more clear, then did the same with the zip tie and then fed it into the hole. Finished it off with the lighter to blend it and it worked. Put another 400 offroad miles on it that trip and 1,000 road miles and some other trips wheeling. October is when i repaired it and it was still holding water as of two weekends ago. Just not the factory weld. Prob something i did, who knows, but I’ll figure it out later.Zip tie welding....never tried that.

And since you don't know the age of your hoses, you should probably replace ALL of them. Don't forget the three small diameter bypass hoses. the "S" shaped coolant bypass hose that leads from the head up to the aft side of the throttle body is impossible to see unless you put your body in an uncomfortable position and an even greater joy to replace. I caught that one leaking on the eve of a weekend trip a couple years ago. Good luck.
I have a similar leak on the driver side. The PHH seems intact and can’t find any dried coolant. It was dripping behind the step by rear driver side door. Any recommendations appreciated.

What year and model truck to you have, that doesn't look like anything I have see on my 80 series, is that part of the AHC on a 100?
That’s hydronic fluid. Looks like the line might be loose. Tighten that nut and wipe off area. Then recheck after you drive for a bit and see if that fixed it
Sorry 100 series. Didn’t realize was in the 80 series threads
