Installed in my 2013 Sienna AWD. Took the family to Florida, drove back and forth a total of 3,900 miles, and they would not have returned home without him. Inflated up to 35 pounds for the whole time. I had a family of 6, 4 bikes, roof rack, tow hitch with spare tire, ladder and pressure washer and it kept me going. Installed with a tee so I only have to pump one valve. A valve is also installed outside next to the hitch. I didn't want to get into a fully loaded minivan to inflate or deflate. I did the same thing on my Land Cruiser. The ride is a little stiff when fully inflated (35 pounds) but heavenly when loaded. Be sure to purchase a pressure gauge and check it regularly. If you are towing or simply overloading a van, do so as soon as possible. If you take a tee and attach the valve to the outside like I did, the installation will be a lot easier.
