Finally got a chance to wire up the dual battery set up. Just need to firm mount everything but it's all wired up and working perfect.
I went with the National Luna set up with 0/2awg garden hose wire and 100amp breakers.
Charge controller keeping tabs on the whole deal.
Ran it to an Optima yellow top and another 100amp breaker mounted where the spare tire was.
Will be camping soon and can't wait to put her to the test.
