The numbers at six weeks in.
5,230 miles.
$998 in gas.
16.75 mpg average over the 5230 miles.
$199 in addition food.
$129 in overnight costs.
Adds up to $31.50 per day so far. (The last few days will add a bunch to the daily average, as I will just be burning miles across the plains. Should stay under $40 per day though, $35 would be nice.)
