I like my 770 quite a lot but “the lady in the box” isn’t quite as smart as she thinks she is... We had about 300 miles to drive mostly on I-70 and she insisted it would take 7 hours. She wanted to route us well north at one point because there was a bridge on I-70 with a 5,000lb weight limit. On I-70?? I think not! She sort of had a fit when I ignored her and “made” me acknowledge that I was taking a risk before she went back to work. Interesting.
