Hi! I am interested in this product. How can it be folded/moved to allow 1 adult passenger on the back seat with the dogs? Also, what is the weight capacity? Thank you in advance.
Overall, looks pretty solid. I just purchased a Tesla model s which doesn’t have an adjustable headrest, and therefore doesn’t have the metal rods that the strap can run across. The model s has just the leatherette material which I assume would get damaged from the straps. Have you had any feedback on this? Also, and suggestions on how to level the floor of the extender as it’s definitely at a sharp angle for the dog to lay on. THanks!
