Installed by us on a 2014 Dodge Grand Caravan. I've been driving it for a year and finally had the opportunity to write a review. We installed it ourselves and it took about 3-1/2 hours. (I've spent some time planning airlines out of sight and installed a schrader valve in the fuel filler flap. I like it when it looks hidden and it was the best way to hide it and have easy access without bending down I check it when I fill the tank and it holds air pretty well but it loses air over time so check it every two weeks I keep the pressure at 20psi all the time because for my application says min 5psi and max 35psi per square inch Our van sunk before we loaded our stuff so this was a must if you want to haul cargo I see other vans on the road with only passengers and he is crouching while ours is on one level with all 7 passengers.(Be sure to take your time and plan. I did two things at once when installing this item. I also have the appendix ger coupler installed and admire my work This took 4 1/2 hours.
