IF the trailers a rockin?

Hello fellow campers, I just traded in my Raptor. I had installed on it the JT Strongarm kit. Boy what a differenct it made in the movment when someone walked thru the trailer. We just purchased the Montana 3735MK. It has a different support system. But boy can I feel the movement. Has anyone seen the kit for it to stiffenin things up like the JT Strong arm? :?

Thank you for your advice,
Dave
