Unfortunately, manufacturing of trucks change from year to year - it is impossible to have a complete list of vehicles that our racks can fit. This rack is mounted directly onto the truck bed - under the lip of the truck bed, as well as being secured to the floor. please note: If there is a bedliner, modifications to the liner may be required - some people do not want to modify the bedliner. Once you are satisfied with the placement and mounting of the rack, you would secure it with self taping screws to the base of the bed.
We recommend that you do not exceed rated weight capcity of the truck rack, evenly distributed - which is 250 lbs - and not to exceeed rated weight capacity of the truck (refer to trucks Gross Vehicle Weight Rating). Secure the load securely to the rack.
When transporting equipment, be mindful to inspect before each use; Strap load securely; Do not exceed rated weight capacity of the truck rack, distributed evenly; Be aware of dynamic loading; Do not exceed rated weight capacity of the truck (refer to the trucks Gross Vehicle Weight Rating).
