I bought this "just in case" because some reviews of the Haloview MC7108 rear camera said the included bracket was too short. I have a Grand Design Momentum 351M toy dump truck and there is a canopy under the camera mount. I ended up using this extension to give the camera a little more distance so it could see over the canopy better. I don't think I would have needed it if it wasn't for the canopy. The supplied adapter plug was not used as the camera was already suitable for pre-drilling the furrow.
