I agree. That's what I was saying, although maybe I wasn't clear:

The 17' uses a small box for one battery or two separate boxes for dual 6-volt on the rear bumper, so there is no "one big box" option to get from Escape. If you want a custom battery setup later, there's nothing for Escape to do - you just install whatever box you need when you change the batteries.
The 19' uses a small box for one battery or two separate boxes for dual 6-volt on the tongue, so again there is no "one big box" option to get from Escape. If the front cargo box is purchased, it replaces the individual plastic battery boxes, and would accommodate a non-standard battery setup without any custom work by Escape.
The 21' and 5.0TA use a battery box in the interior. These
are the models for which the larger box (usually used for the dual 6-volt battery option) could be ordered, with just the basic Group 27 battery in it.
