Converter upgrades are common. I did my 2004 camper.
I recommend if you can get a Progressive Dynamics brand with the charge wizard to fit in your setup. It gives you 3 stage charging and a desulfate mode.
These guys PD9200 Series RV Power Converters - Progressive Dynamics
They make many types and some with AC and DC fuse panels if needed. See their site
I bought mine from these folks. They sell many brands along with the Progressive Dynamics. BestConverter - Converters, Inverters, Electrical Supplies, Electronics
Hope this helps
