6V vs. 12V Ah equal?

What brand of battery separator are you using?

I have checked all of the above and they look good. I currently have the camper using all possible lights fridge etc to draw the batteries down to test again.

FYI, the VSR is a BEP Marine 100 amp model. The paper work references the clicking I heard but to my novice understanding of the system, I can't make heads or tales,of it:

"The charging system must be correctly sized to the batteries. If the charging system is too small for the batteries the VSR system will not work properly. Once the starting battery has reached the right voltage and the house battery is connected, the systems voltage will cave down below 12.7 volts and the relay will automatically disconnect. The voltage then rises, the relay re-engages: then the voltage drops, the relay disengages and a buzzer-like sound will be heard as the relay quickly switches in and out. This also occurs at idle (low amps out due to slow speed of alternator) if the house battery is at low charge. Increasing the engine rpm will increase the alternator output and hold up the voltage."

My truck has 170 amp alternator so I wouldn't think it is to small. Also, the scenario above seems to replicate my situation exactly but revving the engine(driving) didn't result in any charge.

Pianotuna, if I am understanding you correctly, if my truck battery is fully charged, are you saying the VSR won't allow my camper battery to charge?
