The air mattress you show here is 35½ inches wide, but the back seat of the Tacoma is a real tight fit. There are other ones on Amazon that are more like 31½ inches wide and that would probably fit the Tacoma much better. They're a great thing to have in the car in case of an emergency when you'll have to sleep in the car, just make sure you measure the inside of your back seat area and pick an air mattress that would be a good fit.
