Could you please share the detailed specifications for the products in question? Specifically, I'm looking for information on the widths and heights, both above and below the ground level.

Additionally, I'd like to know how drivers access and exit their vehicles once inside the product. Understanding the entry and exit points is crucial for us to evaluate usability and safety. Please include any relevant details or diagrams if available, as this will help us make a more informed decision moving forward. Thanks!
