Charging antimony-free VRLA batteries without float
Here is a proposed much lower float current method to charge non-antimony batteries. Supposedly better than traditional float. Low current float for AGM

The test procedure was interesting, but you title was misleading.
Your title stated charging "without float". The test is "low float".
Also; the article is for a proposed better method to charge batteries used to power emergency lights, critical computers, etc., when 120v, ac, power is lost.
These batteries spent 95% of their life being "float charged" until the time comes that they actually get used. Because of this the battery life end up short for batteries rarely getting used.
I fail to see how this could help any of us for RV use, unless the RV has been stored for a long winter (like the current). My 9-watt, 0.625 amp, solar panel accomplishes this goal for me each long winter.
In your case you get out much more often and need to recover to "full" charge much more often. I guess what it really means is that if your batteries were really "fully" charged, if you could manually lower your float charge to the very low "float" it MIGHT help in the long run. Not an easy job since you need to know the discharge rate of each battery being stored to calculate the lower "float" rate.
