Parallax/Magnatek is horrible.
That depends.
Modern 13.8 fixed voltage Parallax RV converters are just fine if expected and used to do only what they are designed to do ... provide up to 45 amps of DC current at around 13.8 DC volts.
For example, we use dry AGM batteries in our RV. They charge fast at any charging voltage because of their internal resistance being lower than the internal resistance of regular wet lead-acid batteries. Our particular brand of AGM batteries also are to be floated at 13.5 to 13.8 volts (their manufacturer says so). So .... our AGM batteries both float and charge well enough at around the 13.8 volts from our Parallax converter such that I see no need to not use the Parallax unit for everything. I never bought another "charger" just to take care of RV battery charging. FWIW, our RV's AGM batteries are now 8 years old.
