I installed the Plug It Right Stablizers on our Pinnacle.
They offer just the front stablizers or the front and rear stablizers and are lower cost than some of the other brands.
Easy install, took about a hour to install with a battery drill using a nut driver.
All hardware suppled with self tapping screws that worked great with no drilling needed.
Our Pinnacle is rock solid after the install, much better than the tripod we had our our previous Eagle 5th Wheel.
