Question:
Hi, I getting ready to purchase a 2007 Keystone Everest 345s with a sidewinder pin box. I dont need the sidewinder because I have a long bed 2008 f350 . What is the pin box number so I can purchase a air ride set up? Im looking at the lippert flex air. What do you think about that kit? Thanks for your assistance

In order to know which model Flex Air you'd need, we'll need to know either the part number of the original pin box or the part number of the Sidewinder. Closely examine the Sidewinder for a part number. If you can't find a part number, we can figure out which one it is by measuring the spacing of the bolts used to connect the Sidewinder to the fifth wheel.
I'll link you to an FAQ article that explains how to measure the center to center bolt hole spacing. If you scroll further down the page, you can see a table showing the measurements of various pin box models. If you can let me know the 2A, 2B, 2C, 2D, 2E, 2F and the 3A, 3B and 3C measurements, I'd be happy to help figure out which pin box you have.
The Lippert Flex Air would be an excellent choice for improved ride quality.
