Do Coverking covers fit conversion vans?

In most cases no, Coverking covers are custom made for a specific application and any alterations from the original vehicle can affect the fitment. Below is a photo of the seat from a 2017 Pleasure way motor home but the intended pattern is for a Dodge Sprinter as you can see Pleasure way changed the original pattern to include a larger armrest.  If you are unsure about your conversion van please feel free to contact Coverking directly at 714 850 0303
