We traveled from Georgia to Las Vegas in February for the birth of Grand Child no. 6. in 5 days. Now heading back taking maybe 3 weeks. We took I-10 out to Vegas before the storms and flooding. Now on our way back. took 15 up to I-70 and across. a few rough patches on 70 and 1 tunnel with a 13.9 ft clearance Heading towards Vale and Denver. Our Garmin did route us off I-70 around Topeka to Kansas City for tolls. About 45 mile on a 2 lane highway. Not to bad. Now we are stopped in St. Louis headed ( we aren't sure.) Pretty easy route especially since we are new owners with less than 100 miles in our 36 ft. class A. Have fun and safe travels.
