The fact that you are asking leads me to believe that you don't think it possible! Let alone probable. For us we would not even raise the question. It would be a resounding NO! This would be a hurried 7 day trip for us or a comfortable 8.

just my oponion, worth what it costs, nothing. wife and i came from north pole alaska to asotin washington the last three winters pulling our 28 ft toy hauler in a little over three days. then we go to frankfort kentuckey and stop first night at nephews in caldwell idaho then it is three days to frankfort. that being said i used to drive for a living so am used to it but it is still very tiring, if i were you i would try to put one more day in your trip if possible if not it is doable but tiring.

I can't figure out the route you took from Cheyenne to Casper. It is only 178 miles from one to the other.

When we lived in Seattle area, we made a number of trips to Cheyenne to visit family. No matter what route we took, it was always two twelve hour days. The interstates we would do 75, the back roads were less with towns to slow down for. Shortcuts resulted in less mileage, but not less time. When we lived in Alamogordo, NM, the trip from there to Cheyenne was eleven hours. From Wichita Falls, I would say you will likely fall a little short. You don't want to arrive in Seattle worn out, the traffic there is some of the worst in the country. Four days is more realistic, safer, and allows for those inevitible delays. Have a good trip anyhow!!
