Approximately 225 miles west of Ft Wayne on I-80 at exit 81 is Hickory Hollow CG that is 2 minutes of the Interstate, It is a big rig friendly CG that has a pull thru area that would be friendly to you with no need to unhook your Toad. It is in the Town of Utica Illinois which also has a Great State Park, Starved Rock, However, the CG at the state park is not big rig friendly!
I have camped at Hickory Hollow often and it's a Great place to camp.
If you would like to PM me with any Questions feel free as I am very familiar with the areas!
