“What is the TRUE minimum width of window to install this unit? Width of unit is 18.5 inches. My replacement window is 22.5 inches wide. Can I still install this unit and why do they state a window of 23 inches is required for a unit of 18.5?”

Let me answer my own question since I bought and installed this unit. I don't know if all replacement windows are like mine but my outside vinyl opening is 22.5 inches while my inside sill is still the original wood with an opening of 28inches which accommodates the side panels with no problem. Simple installation with no added steps.
Sorry, there was a problem. Please try again later.Because the sealing pleats only collapse down to 23". You can make it work if you want to fabricate your own sealing method though, depends on how well you can improvise
Sorry, there was a problem. Please try again later.The true minimum width is 23 inches. This is the measurement the manufacturer has specified.
