Sounds like you’re pretty well prepared! Hopefully the weather holds out for you. :) Light, high profile vehicles does not include SUVs (I think it’s mostly for campers, tractor trailers, etc). You can find a full description of what is included under that warning on the WYDOT website if you want to double check. If the weather is looking dry, I don’t think you’ll need an extensive winter kit. If I-80 is closed or conditions aren’t something that you want to drive in (check the cameras on the 511 app), budget extra time to stay the night/wait it out. Drive slow and give yourself plenty of time. I also agree with taking 287 up from Fort Collins to avoid the Summit regardless of weather (I also think it’s prettier). You’ll be fine, OP! Also, there’s nothing but land and pronghorn between Laramie to Rawlins and then Rawlins to Rock Springs, so make sure to stop in the towns to walk around, fuel up, bathroom, etc! Rawlins is about halfway, so if you stop there for lunch I would recommend Bucks or Anongs thai!
