One thing that you need to keep in mind is that the higher the speed that you are travellinng at the hotter the engine will run, stay arround 60 mph and when you come to hill country or grades do not use the over drive, when the transmition starts to shift up and down and up, that is when they start to overheat, turn the over drive off and go up the hill, if the incline gets steeper, do not try to maintain a high speed, slow down a little and if needed down shift again.
We sometimes place a bed sheet as a divider between the overhead and the front cabin, this gives us cooler cabin and when we get to the camp ground we turn the roof air to max as soon as possible, leaving the engine running until the engine temp has gone down a little, normally the time it takes me to hook the electric and water.
Drink a lot off water, alcohol is not to good and sugary carbonated drinks do not help at all, we mix some fruit drink with water to give the water some taste, more water than fruit drink, and try to stay in doors with the A/C on during the hottest part of the day.
If you are pulling a toad, cover the front window while driving and when parked, the steering wheel can get pretty hot and leave the windows with a very small crack to let the hot air out, when getting in open the doors before going in to let most of the hot air out, do not leave pets or kids in vehicles in the sun and take water and a drinking bowl for the pets, and carry plenty of water for drinking and belive it or not carry warm clothes in the car while out exploring specially in the desert it does get chilly at night.
NEVER EVER cross a road with running water, you do not know how deep the water is or if the road has been washed away, flash floods kill.
