would a PDC 9200 Series Deck Mount be a sufficient converter to use on two grp 27 batteries
That's probably one of the better converters, as far as converters go.
However, even with the charge wizard, which allows one to keep the Vabs up to the voltage set point (14.4v), the voltage output may be a little low. Do you boondock often? Do you charge in cooler weather? Do you properly top charge and/or equalize? Do you concern yourself with temperature compensation? If no, and you will be on hook-ups most of the time, then the one 14.4 Vabs setting will be fine. Otherwise, you may want to consider an adjustable voltage charger, as opposed to a converter. Just a few things to consider.
Also, best to check the manufacturer's charging voltage recommendations.
