Charge controller recommendations
I have a small solar charging system consisting of two 12v 75w panels wired in series and a failing cheap MPPT charge controller. I may be acquiring another identical panel too. I'm currently leanin...

IMO you can't hurt the batts with a "too long" Absorption Stage while camping; there isn't enough time in the day.
smk's issue is storage, where the controller kicks off every new day by trying to get the batts to 14.6 Vabs, where the ideal would be to stay at 13.4v or whatever all day.
If you can't stop the controller from getting them to 14.6v every morning, then at least you could shorten in the time the controller stays there before dropping to Float.
The question often asked and no answer seen yet, is how that really compares as a Float with shore power float using a charger that stays at 13.4v all the time. ( The "solar being off at night--does this make up for being on 'too much' during the day?" question.)
