Route advise from Wisconsin Dells to Indiana Dunes SP

Hi All

Thanks for the suggestions. I will take the I39 to I80 route as suggested. I will try to stop at the cash booths, as I don't have a navigator and I have read that you need to know the time and which toll booth, and I think that might be hard to remember when I am driving. Also I am from Canada with Canadian plates on both the truck and trailer, so not sure which they would use. We only have rear licence plates in Alberta.
