Howdy from Jackson Hole!
Here's FWC manuals and owner info few (including dealers) know about: https://fourwheelcam...ck-bed-campers/
The most recent covers 2017, which is very transferable to succeeding years. KNOW: This manual gives incorrect part numbers for Yakima racks. While stating they're for the round bar style (now longer marketed) they're actually the "streamlined" less load capable "modern" ones. If Yakima has phased out what you need, go to Ebay (often cheaper).
