I am not sure about Alpinelite TC's. When I had a Lance TC it was attached on each corner to the truck with chains and a spring shock type attachment. There are much newer types on the market now. These attached to a bracket on the front of the truck bed, and the rear attached to a special bar that came out of the side of the trailer hitch receiver. Normally the rear would attach to the rear bumper. The TC must also be electrically connected to the truck. Lance had their own connector, Alpinelite might have their own also. After I purchased mine I learned so much about center of gravity when mounting and whether it could even be mounted on my truck. JMO
