The BEST RV friendly gas station I found is on I-65 coming down from Wisconsin. I think its on the Illinois side.
It is a Shell Station that has it very own gas island just for RV's way away from the other pumps easy in and easy out.
AND......drum roll.....It actually has 6 drive thru campsites right at the gas station! :B
They are side by side and on full concrete and FULL hookups!! For those RV'ers that need a stop over while traveling.
Wish Shell would put up more like this. I made it a point to stop there every time I'm on 65.
IMHO the ULTIMATE RV FRIENDLY gas station. :C
