Yeah Polman that had me a little perplexed. I know the value line has that integrated skid plate if you will that is actually part of the frame. It's mistaken all the time as a skid plate but it's really the frame. Think along the lines of guardrail and guiderail, same thing but legally do two different things. But seeing as it's a 2021 I thought maybe they had added some plastic skids like they do on the XPs. I know they removed the a arm plastics.
In any event OP you install your new aftermarket skid plates over that existing belly plate is that is part of your frame and not removable.
