Look online for Winfield stablizers. I put them on the back stabliizer jacks ( modified the jacks to accept the 3/8 inch bolts), did not want to cut into the insulation of the glacier package of the 27dsrl. These are the only ones I found that do not require you to mount to the frame. Work amazingly well!. Very little rock noticed after installation.
