Personally I wouldn't swap out your converter just because it's a WFCO ... try it first for awhile, then if you find your charge times are longer than you'd like that's when it would make sense to consider a more capable charger.
I agree except you can immediately know by measuring the voltage.
Leave a light on and run the battery to 11.9 to 12.2 volts and then plug in. Voltage should steadily rise to 14.2 to 14.4 volts and you are good.(let charge 24+ hours) More likely 13.4 to 13.6 and you have a dud trickle charging WFCO that needs replaced. Do not wait for the big boondocking trip to find this out.
