I found that campgrounds are the biggest variance (but I don't cook on tour). I like hiker/biker sites at $5 a night where available, with the odd hotel room thrown in (hello Motel 6). Sometimes you can't avoid the $40 campsites, though.

Food I don't track or budget for. I have a couple pieces of fruit for breakfast, restaurant for lunch and a big sandwich (like a subway or Safeway deli sandwich) for supper. Plus snacks through the day.

If I'm pounding through 3-5K calories a day, I eat whatever comes close to me
