My deep cycle trailer battery went dead due to a parasitic drain. Normally I disconnect but it was at Camping World for a repair…Anyway, I charged it up and checked the specific gravity of the cells, two of them were slightly lower than the rest (both outboard cells interestingly enough). All were good, those were in between fair and good. I then did a load test on it with a carbon pile and it did fine. Should this anomaly be overlooked and just assume that the battery is fine?

I'd say if you don't depend on it for a lot of boondocking work, I'd just send it. If you mainly park camp and have a source of AC, then you can always keep the trailer plugged in to run slides and tongue jack if the battery fails.
kind of my thinking until a national park trip in october
Can you put it on an old school charger for a few days? Low amp setting (like 3amp) and let it gurgle for a bit. A flooded deep cycle can be a very durable battery. I would not even blink if a couple cells were a little different - needs an “equalizing charge” which is a gentle, long, slow, overcharge.
