From personal experience I would only utilize a true deep cycle battery if indeed you need a deep cycle. The two I had didn't like being used in a non-deep cycle environment: Both failed: 1 at 12-months the other at 14-months. Since installing a non-deep cycle battery in my non-deep cycle application: Zero issues.
Secondly: I have set my dual battery system up for sharing. I run all the stock vehicle loads off of the main battery and I have set up a second isolated circuit (PowerGate) for the second battery (fridge/freeze, trailer batteries charging circuit, winch, stereo, etc.).
There are different philosophy camps when it comes to dual batteries. I prefer the one that says: Use both batteries then the second/back up doesn't get conditioned to zero load. And by that virtue both batteries get used everyday and I can keep an easy 'eye' on the spare/aux/2nd/back up battery (call it what you want) battery everyday.
Just my $.02
