March/April Trip MN -> Grand Canyon -> Vegas -> Utah -> MN

X2 on the above ^^^^. My favorite WX guy says winter will NOT be over that early so go south and then West since you do not have time to sit it out. Last week I came from Phoenix to Atlanta and used I-10&20 instead of I-40 because of likely bad WX. I was impressed with how good I-20 was the majority of the way and by doing Dallas at midnight sailed right through. Two years ago I used 40 and it was rough in many places plus lots of construction...not so on 20.
