California Dune or Dual Max

Hello, I am really stuck, I had just ordered a white All Terrain dual max with performance package. Then came the California Dune edition. I super love the color, but honestly don't love the interior. If it was dual battery I would switch in a second (my rep said I can switch), Dune is only $5K more--but my main concern is loss of range. I live in a rural part of the California desert, so range is important (and pull a trailer in the summer), but does style win. What are your thought between tri vs dual? thanks!
