That's definitely a possibility. The difference between RV fresh water tanks and marine ones seems to be an access hatch for cleaning.
I've seen some pretty ugly messes in marine tanks.
I'd do the bleach treatment but let the water drain into a pan and see what comes out. If there's deposits coming out I'd probably repeat the process, maybe also going for a drive to agitate the mix.
I don't have foam covered tanks and I'm surprised that there's no indication of mold. I thought that almost clear plastic might suffer more from mold but apparently not.
