New Cruiser MPG 2400BH battery draw issues...
So we recently purchased a new 2016 Cruiser MPG 2400BH trailer...... And the fun begins, first day home and the batteries are so low that the awning will barely move. Figuring that the dealership forg...

Smaller wire between solar panels and battery will reduce charging efficiency, but won't prevent a full charge - as the battery approaches full, the current and therefore voltage drop goes down. It helps to have a controller which has remote voltage sensing, but that's minor. If the difference between good and bad is a few percent, you're going to be in trouble during extended cloudy periods anyway. Remote temperature sensing is more important, since it effects the lifetime of the battery.
Beyond looking for unexpected high loads, it may just be a matter of voltage drop between the battery and the loads, and where the LPCO detector/Low Voltage alarm is wired in. You mentioned it going off even when the battery is at 90%, so maybe you don't have a real battery drain issue.
LPCO detectors draw minimal power (<100 mA), so it may be a simple matter of wiring it in so it connects as close to the battery as is practical so it doesn't see the voltage drop when large loads kick in. 18 or 20 ga. wire should be fine.
