I just traveled from Denver to Cincinnati using I-70 & I-74 Thurs. & Fri. No issues but lots of salt on roads. Watch weather reports before you go. On the way west before Christmas we had rain for 550 miles then it turned to ice, so we stopped for the night. I didn't do this trip in our RV, used our Subaru. Next day we had snow and ice for 100 miles. Just pay attention to the reports, park it if you need to.
