I would ditch the on-panel charger; get a $20 e-bay PWM charger and mount within a foot or so of your battery. With one 120 watt panel, I'd set up so that I could bypass the charger and tie directly into the battery when I knew the battery was below full charge.

Yes. Panel-direct till it gets to 15v (if it ever does that day) and then connect the controller so the fridge etc does not get over-voltaged. So no concerns about a too-low set point.
Also if you will be away from the trailer that day when you think the battery voltage will hit 15v, then you can leave the controller on to prevent over-voltage (which is what it is mainly for anyway)
