Refer fans for improved cooling...what are the best options?

We use a shade that we set up to cover the fridge area when the sun is directly facing it. It does not cover the entire roof area, but it does cover the side of the TT. We have done this in Death Valley and Arizona, New Mexico, and Texas. It made a huge difference from before we used it. We are in our TT now in 100 degree daytime heat and fridge maintains the fridge at the bottom of our thermometer's safe zone set at 3. We have not needed an exterior fan, but do use a fan in the fridge.
