The Mitsubishi configuration tool is simple and effective with a dynamically changing left-hand image and a right-hand long scroll of configuration options.
Detailed specs are somewhat scattered across the experience, requiring users to navigate to other areas of the site if they want a comprehensive overview of more detailed tech specs. The 10-year warranty messaging throughout is compelling, but the overall experience could benefit from better integration between the configurator and detailed specifications (accessible via a separate compare tool experience).
