I'm a new owner of the CRV Hybrid 2021 and a new dog owner. I am struggling to measure the interior dimensions of the trunk/cargo space--each time I get different dimensions at 11.5 and 23 inch above the floor and it is driving me mad

Has anyone measured and marked them down and can share? I'm trying to figure out if this crate (Ruff Land Intermediate SUV) will fit into the cargo space nestled up against the seat back with the door facing the trunk door.

Its the smallest crate that could work for my dog
