…. just wondering how you got to Victor.
31 to 26 to Alpine is the best way out. It's an easy drive - no drop offs. Ask the park office where you're at about the route out. You could also drive the 31 to 26 route with just your car to see how it is before taking the RV.
Purchase the Mountain Directory for Truckers and RVers and you can read all about the roads before you drive them. Have you tried putting on a sleep mask and getting comfy on these drives? Perhaps if you don't see the gorgeous views they won't bother you. I hope you can overcome this because all the scenery is on these types of roads. You don't have to drive extreme routes to see the beauty. Hwy 22 (Teton Pass) is what I would consider extreme. Good luck!
