I want to add additional full width images/carousel and text between the default woo product display and footer area.
The information may differ for different products.
What is the best way / tool to configure this?
TIA.
What you can do is install Toolset Views, Types, WooCommerce Views and WooCommerce, and after creating your products, you will style them with a Content Template.
In there, you can add a View at the bottom of the template that shows the slider as you will style it in an appropriate View.
The content of this slides can be taken from a Product itself, or another Post type that you can connect to the Product type.
However, the content template will just replace the content part of your theme, hence making "full width" a relative status.
It'll depends on the Theme's Full width settings, as the content Template will just replace the_content() part and not the entire Template with sidebar and header/footer.
If that is enough for your, then this is the Documentation you can follow in regard:
