I guess I am in the light duty category. I have 2 Sam's Club 6 v GC batteries. I charge with a 40 amp B&D charger to Ful then let the old Magnatec 950 charger float at 5 amps for a couple of days before I go camping. This usually lasts me about 7 days before I get to 50% SOC. The 5 amp float seems to give me several more days. A .........
I have that charger and 6s too. To properly charge the 6s, once the charger says Full the first time, change it over to the Equalize function and 4 amp setting (green light flashing) and let it run till it says Full again. After that put them on your Float charger.

You need to confirm that the one Equalize run did raise the SG, and it could take a second Equalize run to get the SG right up where it belongs. You will soon find out what your particular batteries want.
If the old converter's Float is too hard on the batts, you can get a decent float charger for about $30 that stays at 13.4v constant and use that instead. I agree with keeping the working old converter and using portable chargers instead of swapping out the old converter and re-wiring the rig (to get value from the new converter) where it is just too much trouble to do that mod.
6s do need watering for sure. Even sitting on solar for weeks getting some 14.x voltage every day also means checking their water
