We have had one trip with our 310GK-R and like most of the features of this RV. Grand Design did a good job with the QC.
I have one issue. With the residential refer, there is a second battery. We have had AC power ever since purchase and the main battery tests at 13V. However, the second battery tests at about 5V to 6V. When the inverter is on, it shows 11.6V.
From the picture, you can see that the positive terminals are connected -- red cable with the yellow plastic. However, the negative terminals are not connected.
It seems that running a 4 AWG cable from the negative on battery1 to the negative on battery 2 should help. In our last RV, I had three 12V batteries and bought three sets of cables. The positive and negative leads connected to all three, so there was total balance. It seems to me that there is a battery balance problem with our RV.
I have a cable on order, but have not installed it yet. Is this the best next step? It is not total balance, but it would be an improvement.
