Converter and AGM type batteries

We are considering replacing the wet cell "marine" battery that came with our 2006 3055RL #4066 with a AGM type of battery. From what I have been able to read on line here and at RV.net, the AGM batteries are more fical about how they are charged. Is the converter in the Bighorns compatible or will have to replace it with something else. If so, what would you suggest?

I am going to have to ask for help on this one - because I just don't know. Any owners out there who know how to answer this one. If not, I'll do my best to track it down with Progressive (the maker of our power convertor).

The new 9200 series has the built in 3 stage charge wizard the older 9100 series you have to use the external charge wizard. On those there is one for AGM batteries and one for wet cells. You have to let them know what battery you are using when you order one. The newer 9200 series you can order the manual pendent but I don't think there is a difference in those.
