Victor, ID to Chicago, IL

Thanks for the route info.

191 is fine, like CloudDriver mentioned, the hardest part is through Hoback and it's not even that hard and not too windy. It flattens out pretty much after that. Bigger issue through there is the wind can pick up, especially once you are out of the mountainy area and closer to Pinedale. We nearly flipped our old travel trailer on 191 between Pinedale and Rock Springs due to wind, but we also had an undersized truck pulling it (upgraded trucks after that trip) :) I wouldn't be worried about it in a proper rig.

Route 26 and 89 are easy drives. After turning onto 191 at Hoback Junction there is a modest climb for a few miles then essentially level all the way to I80. Nothing like going over the Teton Pass, which you already know not to do again.

This thread from a few weeks back had suggestions for using route 31 from Victor to get to route 26. No personal experience with that route.
