We also took the Cadillac, but, I considered the Chino Valley - Perkinsville stretch of road too easy, so the Caddy took that route, and I went north to Drake and then took the Drake-Perkinsville stretch of the road. In worse conditions (recent rain + heavy traffic) and still had a few water crossings.
Here are some of the pictures, and I had a friend take some pictures of me crossing the water


You might be able to see the new antenna bracket I'm designing and improving (the aluminium thing on the rack side rails)
