Dateland, AZ to Oceanside, CA

By far the shortest way from Dateland AZ to Oceanside CA is I 8 west to 805 north to I 5. I 8 west is a radiator tester from Ocatillo to the top. Altitude change is + approx 4,200 ft in a short distance. I did it in January two months ago and it was still cool. I can do it in July too, but I have a recently cleaned radiator and a lot of excess power.

If you have any overheating problems at all with your rig take the grade first thing in the morning or after 8 pm. It get really hot on that grade in summer. There are several water stations on the way up. I frequently see overheated vehicles on that grade in the summer.
