You should have no issues with your DP and I-80 it sounds like. I-80 is a popular route for trucks and some RVers don't like that but I find running with the big rigs not a problem-probably more confident around these professional drivers than many in their automobiles. Your post mentions that you are headed to Central IL and I would think I-80 would be the most practical from a distance issue but, I don't mind traveling the Great Plains either. We just returned from the Springfield and Champaign area on our way back from Lake Huron and we used I-74, US 36, I-29 and then I-80. Perhaps your destination will determine which way is best? I-90 may add more miles than you want to do. We are headed west on I-80 in a few days-perhaps we'll cross paths.
