Proper float voltage depends on temperature. eg, at 80F =13.2v and 50F =13.9v When it gets cold you can get into the mid-14s
So any charger that has a steady Float voltage will be mostly wrong. If it has too high a voltage for the temp, then you will need to add water to the batts as required--keep on that and you will be fine.
If the Float voltage is too low, then your battery will stratify and so get sulfated and lose capacity. (but it won't lose water :) )
Time is everything here. If you are only on Float for a few days at a time it doesn't matter.
You have to adjust to the situation you are in what to do. You can get temp compensated chargers for doing your Float if need be. or you can goose the voltage up on the batts every so often to get rid of any stratification happening.
