Nobody really has to offer up a Raptor competitor to make sales. Let’s be honest, the Rap is a capable off road truck that excels in the desert ( or dessert, depending on the drivers ). Jeeps are more maneuverable and narrower and tend to be more favored among the rock crawling crowd. For mudding and typical “east coast” lower speed off roading, a regular f150 eco with a lift is plenty capable. Sure, the Raptor will do some things better, but it how much better time are you going to make headed to the deer stand in the Raptor as opposed to a Chevy, Dodge, Taco/Tundra, etc?
If someone offers up a less expensive truck that’s close, they will definitely eat into Raptor sales.
