I am new to this post since I recently aquired my 5th wheel. Getting ready to retire and roam the country. I have a 2012 Sierra 330RL with from hydraulics landing gear. Is there a way to override the system if the battery does dead? I could not find the solution. The rear landing gear are electric and that was easy to overrride. Thank you for your help.
