Regret solar may not be in your future.
Seems the easiest way to get a battery to FULL by holding the battery at a constant voltage LONG ENOUGH. A small system to top off / maintain at minimum.
Almost any big charger will charge you batteries to 80% or better on a daily limited generator time. morning generator time shouldn't be over 90F so 14.4v is fine.
To me what is important that after days of undercharging that ya FULLY charge, and then maintain till the next session of daily undercharge. Solar makes sense for that.
Hope your new setup draws you out to more dry camping as life events change.
