grand design 337rls self level

I don't have a Grand Design, but I do have the LCI 6-point leveling system. I will never not have automatic leveling. Hope that helps

Grand Design does not offer factory installed self leveling systems in the Reflection series trailers.

Your dealer can install them before delivering your trailer, however. There are a number of different brands and systems, both hydraulic and electric, available.
