If it was me doing this, I would get a solenoid isolator, basically a continuous duty starter solenoid, mount it on the inner fender near the secondary battery, run a ground wire to a good ground from the secondary battery, run a hot positive 2 to 10 guage wire from the secondary battery to one side of the solenoid, a 2 to 10 guage wire from the other side of the solenoid to the primary batterys positive terminal, run a smaller wire from a hot ignition-on terminal to actuate the solenoid when the key is turned on, and call it a day.

All sorts of ways to go about this, and every single one always has one or more significant disadvantages to it.

Another approach altogether which is entirely safe would be to fit a second alternator to charge the second battery, and leave it totally separate from the existing vehicle electrical system.
This has been done many times for campers, off road, and the high power car audio people.
You can run that sucker right down to zero, and there is no way it is going to immobilize your vehicle.
