The cali does not have a heater, it has a furnace.
I could not sleep last night. -3 degrees in Arras, first I froze, then put heating on and baked. Even on the lowest setting earlier in the evening I had to take my fleece off and sit wearing a lightweight top.
For all the criticisms of the Cali it really is a beast when it comes to tough conditions. Would not want anything else to rely on. I feel totally secure that even if the wardrobe hinges fall off, the waste tank sensors don't register, the moo valve moo's at me, when push comes to shove and conditions turn nasty then that vehicle will get me out of trouble.
The more I drive the more I am impressed.
