Battery disconnect switch

I have a new Jayco Whitehawk 27DSRL with TWO batteries and want to install a battery disconnect switch. Is there any reason to get the 4 position switch to enable disconnecting battery 1, battery 2, or both? Or just get the 2 position switch to disconnect both batteries at once?

Next question: Blue Sea or Perko or other; which is better?

Does it matter if you place it in the positive or negative line?

    Here is a decent Blue Sea's, M series, 3-position mounting

    If the batteries are 12 volt connected in parallel & you wish to keep them that way, then a simple on/off switch will work.

    Either Blue Seas or Perko, both are good.

    Many switches you purchase will connect to Negative, but I really don't think it makes much difference. I've done mine through the negative, either way cuts the circuit.
