Idiot lights as they are known have one redeeming feature. They allow the salesman to explain what a great battery monitor you have!
Why are you using a small charger for the house battery vs the house charger that came with the rig?
Discharged flooded batteries should bulk charge at 14.8V. A 4A charger is inadequate but left on for days may charge the battery. If the battery is NOT completely 100% disconnected then house drains may account for the 12.5V.
From your post the battery is not being fully recharged and it may have less capacity due to being under charged for the winter so far.
BTW 14.8V is for 70F and the temperature corrected voltage is higher for a Montana winter. Even up to 15.9V, something to consider.
