This is a belated response to your request for stories about travel food memories. When I was about 8-12 years old (roughly 50 years ago)my parents took my sister and me on a few road trips. We camped in a tent and ate food cooked on a campfire or a little gas campstove. But that's not the food I really remember. No, it was the A & W rootbeer floats! My parents were not financially well off, and our big treat on these trips was a stop at an A&W for a float and, rarely, burgers. I suppose they tasted better then because they were such a rare treat.
