BRAT (at least last year) was $300. The fee included most breakfasts and dinners. Lunch is generally not provided, but that's largely because you're on the road during lunch, so you eat what you find along the way. SAG stops with snacks and drinks were provided when there was otherwise no place to stop, i.e., in isolated areas. The food was actually generally pretty good and plentiful. The fee also includes park entraces and tent camping. You either have to provide your own tent or pay extra for an independent service.
