We're headed from Milwaukee to Mesa starting on the 26th of this month. We've done this route a few times, always successful. The key is to pay attention to the weather! So far you could say we're "lucky" but never had any serious issues weather-wise. Two years ago we postponed our trip by about two weeks due to the freeze that took place in southern the states. Arriving in OKC that year aprox. half the RV park we stayed in sustained water line damage to almost half their park, so weather is for sure a real concern/danger!
Just have to be aware and adjust for the weather, a few "weather" days planned into the trip is the practice we observe. YMMV
Good luck with your trip! :B
