Interesting experiences. I have a 2015 NV3500 passenger but I took out all the seats on day 1 and never put them back in, never planned too. I use it as a cargo van. What prompted the question is I had the oil changed and they put 50psi up front and 80psi back which is the numbers off the door and the light came on and is still on. When we discussed it and tried to deal with it he said my psi all around was at least 15 off or it would not of had his tool buzz, as it did. Hmm. He believed the fronts were 40 and rear 65psi when I came in. I know 40 is not 15 off 50psi but that is what he said. I love the way it drove whatever way it was before. It seemed stiffer to me coming home after the change whatever it was. I don't really drive the van around town much and will get a better feel when I take it on a trip on the interstate. Now if nothing else I have to get the light off Thanks for the input Tony
