ADAC experts confirm external sunshades are more effective for motorhomes
Original source: motorpasion.com

The German automobile club ADAC conducted tests showing that an external reflective sunshade on the windshield reduces interior temperature to 45 °C, compared to 49 °C with an internal shade and 59.1 °C without any protection. The difference is due to physics: external shades reflect radiation before it passes through the glass, reducing heat buildup. For camper vans and motorhomes, where the space is used for living, this lowers the load on ventilation and air conditioning.
