I think that is what I'm gonna do (un-hook when not in use)...
Just to be clear about what others wrote above, you need to disconnect the batteries if you're going to do that. Isolate the battery bank. If you don't, parasitic draw will ruin your battery in a few weeks. Personally I'm in the camp that says stay connected to shore power all the time, if an outlet is convenient to your storage site. If not, install and use a disconnect, and be sure it disconnects all loads.

...Never had any charging issues and while my WFCO converter isn't the best I'm told it's not the worst. I'm guessing when it leaks on top it's possibly a bit over-heated or over-charging. If I was to go with a Progressive Dynamics converter would this possibly eliminate the possible over-charging??
My experience with WFCO converters is that it is very unlikely one is over-charging your battery. Just the opposite, they rarely will go into boost mode at all, even though they supposedly have that mode. Far more likely that you overfilled, or spilled.
Progressive Dynamics makes a far better converter, no question about that, and it will give you a proper boost mode and a better charge. But if the WFCO is working for you, and especially if you don't camp off-grid much, it might not be worth it to you to upgrade.
