Mounted it in my f250. Was great for a few days, sounded good and filled tires fast. Then it started getting louder over the next few weeks and filling slower and slower, until while using it, it started not being able to pump more than 20 psi. Have not been able to use it since. Wish I new what part to replace to make it work again. I run a rolloff dumpster business so I really need a reliable onboard compressor. I'm willing to give it another chance if vevor sends me the parts to fix it.
