Shopping for class c, daily cost to operate?

My wife and I just returned from a cross country trip from Fresno, Ca to Atlanta, GA and back. The trip we took included a total of 35 days. Twice we stopped for week-long stays in campgrounds, other nights were single stays as low as $12.50 a night (Passport America)up to $30.00 a night with no discounts. Two nights were at a Flying J or other boondock stop. Our total for fuel and campgrounds without food was under $125.00 a day. We ate in just about the same fashion as we would had we stayed home for those same 35 days, some home cooked, some restaurant supplied. And as Artum Snowbird said...a good sleep in your own bed. Others may differ, but my experience is that the longer you are out and about, the cheaper daily cost you will accrue.
