I've read i few threads but everyone seem's to have there own unique scenario.

I'm running a YT g34 up front and installing a Deka9a31 in back. I'm installing a mechman 270 amp alt. of course all the wire is 0Ga. is one battery gonna eat/kill the other because they are not exactly the same? opinions seem mixed. because they are both AGM does this make a difference for the better?

if you do not drive often you can use a relay type isolator and if you go extended periods where you do not drive the vehicle you should at least disconnect the battery
