I still do not understand why FWC install "duel purpose batteries" in their campers. IMHO your batteries are not being fully and correctly charged. The Tacoma alternator will put out enough voltage and amps to charge an agm battery, but it will take time, depending on the amount of discharge. The guage of wire between the start battery, acr, and house battery makes a difference in what the house battery will actually receive reguarding charge. The arc can be set to a low open of 12.25 if so desired.
Your solar, depending on the set up will fully recharge your batteries. Remember "between 102% and 110% of the discharged ampere-hours must be returned for a full recharge" (http://lifelinebatteries.com/wp-content/uploads/2015/12/6-0101-Rev-E-Lifeline-Technical-Manual.pdf )
As others have said you need a monitor to properly track your charging such as a Trimetric or Victron.
I would also add that the Blue Sea ARC that is a better fit would be the https://www.bluesea.com/products/7700/ML-RBS_Remote_Battery_Switch_with_Manual_Control_-_12V_DC_500A but that's just my opinion based on my professional experiance.
