This information is straightforward. Amy must have purchased gas on a credit card. I would like to see how much fuel was purchased. Almost everyone fills it up. If in fact the truck was full at this point, the total amount of mileage can be calculated and a much denser area can be pinpointed.
Mileage is a key determining factor in figuring out how much she traveled in between Johnson Creek and Rockford. Knowing that she was within 5 miles of Sterling and also stopped in Winnebago we could calculate just how far she would have been able to travel off the main roads.
At minimum she had to travel 286 miles going from Johnson Creek (where she filled up) to Kalahari Resort to Sterling, IL to Winnebago to Rockford Inn. The Expedition she was driving has a 28 gallon tank, so it would be interesting to see (if she had filled it to capacity) how much fuel was left in the truck. These trucks get about 12 to 18 MPG. Tops she could have driven on a full tank of gas is roughly 500 miles. If we knew how much fuel was left in the tank it would narrow down the searching area dramatically.
