Yes, that does sound like a problem (if you're only seeing 13.2V during all stages of charge). You definitely DO want to get charging voltage over 14VDC during the final stages, before the 13.2VDC float. Apart from that, it sounded pretty good except for the lights being on all the time.
Wonder if there might be a reset button somewhere. Do you have the manual? Have you queried Mastervolt direct (not the dealer)? They may have a better handle on it's weird behavior.
Sorry I can't be of more help.
