Using battery charger in place of converter?

I have a 1990 Gulfstream P30 motorhome. One thing that drives me nuts is battery life. If I leave it unplugged, the batteries go dead quickly, and in days I have dead batteries, which isn't good for them. If I leave it plugged in, the batteries get overcharged, which is also terrible for them.
It has a magnetec converter with charger built in.
In the summer, I often leave it plugged in so that the fridge can run on shore power. During that time, I think that the newer trickle chargers would be much better on the batteries. But how do I go about this? I would love to hard wire it, but with 15A output, I don't know that I could rely on it alone for power when we are using the motorhome. If I plug in the charger with the converter charger enabled, then I suspect the converter charger will continue to overcharge regardless of what the charger is doing.
I don't want to invest in a new converter due to the cost. After all, it is a 1990 motorhome, and I don't want to spend more on this issue than the entire thing is worth. :)
Any suggestions?

Just bite the bullet and install one of these... New Converter
Then when you trade it off, put the original back in and find something else to do with it or just sell it. You won't be sorry with the pain you'll save yourself, either.
