Footer Trubbles

I'm trying to set up a site using the Deliver skeleton. I'm setting it up on a subdomain of my current site.

This is the top level page (template modular):
http://www.org.hellbendermedia.com/

Notice how the footer region is the full width of the page.

The same with the store (template shoppingcart products):
http://www.org.hellbendermedia.com/shop.html

But on pages (template default) such as:
http://www.org.hellbendermedia.com/behind.html

...the footer is no longer 100% wide as the page. It's as wide as the text.

I am going nuts trying to figure out what to fix with this. I am trying to look through the various files, but maybe I'm just not smart enough to find the exact little tiny thing that i need to change. I have been tweaking and twiddling for a while and can't find it.

Can anyone suggest my next step?

Looking at the Deliver skeleton pages, you need to add

body_classes: fullwidth

to your page header to make the footer full-width.

Oooooh, I see where it's missing in the code! Now to figure out where it's supposed to be injected and slap some text in there...
