I love my Model S but there are certain places I just won't bring it to. We go off into the mountains a lot -- some are within range of a single charge while others aren't. But regardless, I'm far too protective of my Tesla to take it on rough roads. So my question is, what do people here use and/or recommend as a cheap second car for packing full of camping equipment? Something fuel efficient so I can at least feel a little bit better about driving a gas car. Alternatively, are there car-sharing types of things in the Portland area? Renting every other weekend is prohibitive but sharing a gas car for the bi-monthly camping trip would be preferable.
