Fyi on CVF, I bought and installed a CVF front runner for mock up. A year later, still in the build process I decided to add AC as it's now or never. I contacted CVF about adding the compressor and bracket that matched what I had, and eventually decided to swap out the installed, mocked up system for the top of the line Wrapter. CVF credited my system for the upgrade and took it back, verified it was as I described and shipped me the new one. Don't know of any company that would do that,take back an installed product and give full credit for it, they are awesome to work with.
