With the lights on, the radio doesn't draw much...

Unless you sit around in parking lots, waiting for your wife, while 
listening to the radio with the engine off etc.

There's a reason car battery chargers stop at 10A.  Motorcycle battery
chargers are more like 2A.

I had trouble charging motorcycle batteries at 10a. When I had my CB900 it 
needed everything a battery could provide, after a couple of weeks sitting it'd 
need a charge. A couple times I rushed it at 10a and boiled it, oops...

Two issues with high rate charging, heat and hydrolysis. 
Run it too hot and plates can warp. 
Excess voltage makes the water in your electrolyte go bye-bye. 
Probably the best bet is a 6-10A charger that slowly tapers down to 2-4A at 
full charge and then shuts itself off.
