Along comes Reticulum which
 proposes to build long-arm meshes

This is great! Thanks for figuring out how to get this on Manjaro. I tried RNS awhile back with Arch, but my phone was too buggy to get through the steps to install crashing repeatedly on each attempt, but I'll try again using the method you outlined in the link in the next few days hopefully.

Manjaro came with my PP which worked fine the first day I got it and played around, but when I picked it up a week later the internet kept flipping on and off (among other issues) making it impossible to update the OS over the net.

Is there another way like loading the newest PP Manjaro version on an SD card as just a file (instead of flashing Manjaro on the SD card) to manually upgrade it so I free up the SD card from just being used to boot the Arch operating system all the time?

I decided on Manjaro Phosh,
 after all the agony of trying to keep other distros running.

(I quit KDE back when it trainwrecked version 3.5.10 
 and then Plasma,
 and repeatedly have tossed KDE in the rubbish bin ever since.
 a "Looks pretty, always broke" 'harbor queen')

I am a bit confused about how you boot your PP  ?!?
Are you always booting from the SD card ?
If so my advice may not work for you,
 but just to share a bit:

I remember  installing Manjaro (onto the PP) from the SD card as usual,
 then, in reverse strategy,  installed Manjaro on the SD card (from inside PP),
 which allowed me to repartition the card (which restores the full capacity)
  and then stow new .iso files in the /home/whatever directory of the SD card.
The issue back then was whether the new iso would boot correctly
 because I got annoyingly tired of juggling SD cards.

There are probably three better methods to do that,
 but I am running out of daylight here.

Good luck with your efforts on RNS,
 just ask if you need any help.
