sourdough

I'm curious if anyone travels with a sourdough starter.
Keeping it in the cooler will only work if you'll be camping in one place for a few days. But I didn't know if it would survive tucked away back in the galley. My truck doesn't have air conditioning and I think many summer trips will get too warm in the cab.
And sourdoughs out there with travel tips?
thanks!
