My '04 ext. cab had the flip up rear seats and hinged storage bins. With these out of the way My 90 pound Lab could get comfortable in the back. In my new '16 ext cab The set up for rear seating is not near as good for making room for the Dog. seats fold up but storage bins are fastened to the floor. No flat floor option. Has anybody removed the rear jump seats and storage bins. to get a more flat floor for a dog or just for better storage.
