I turn the main off for the chassis batteries and put a battery tender in that compartment.

This is only safe if you have a converter such as the Progressive Dynamics that will switch to float/maintenance mode when the batteries are fully charged. If the circuit keeps full charging, the batteries will be fried. Some on these boards have reported doing just that. Check your converter manual or specs online to be sure.
