I upgraded my factory WFCO converter to the Progressive Dynamics Intellipower and can tell you it is worth doing. They make converters that are a slide-in replacements for Magnetek and others so that you don't have to change out the whole fuse box....just the converter/charger. I got mine at Best Converter, since recommended by the guys over in the Tech Issues section.
Also check the wire size and distance between the batteries and the charger. In my case I have 25' of wire that was sized at #6. I added another #4 alongside to counteract the voltage drop from the charger to the batteries. (In my case the used the trailer frame as ground so only had to upgrade the POS (+) wire.)
Charging is more effective and this is the first year I didn't have to add water to the batteries after leaving the rig plugged in all winter.
