Well I just read a post from another rv forum relating to the same issue. The guy that made the post confirmed with interstate customer service that the gc2 series batteries need to be charged at a voltage of 15.3v due to the chemistry of that battery series. This is also the voltage specified for absorption on the interstate charging sheet. So this voltage requirement is quite a bit higher than any converter I know of...
Equalization is 15.3V which new batteries should not need. A good charger will have a equalize option.
From the Internet website. Probably best to not read to much from that guy.
