They just introduced this product at our rally last weekend and did not have it listed yet on their website. They also some ladder based mounts you will see soon.
On the same note, StableCamper has a new SuperTruss and Cannon accessory. It is a receiver that sits mid length of the extension at 90 degrees. Now when you drop the camper at your site, you can stow your truss parallel to the rear bumper.
