I'm in Loveland CO. My in-laws used to live no North Kansas City. It was 638 miles to their house. I've made this trip many times. The Traveller is nice around town, and for the infrequent longer trip. That long of trip would be a long haul. Not really an interstate car. It would probably do it, but no promises. I have made the trip several times in Model A Fords, a '33 Ford, MGBs, '65 Spitfire and a number of other vehicles, and never had major problems, but it was always an adventure. If interested let me know.
