In the summer, I specifically ask for North facing sites unless there is shade. reflective material, even on the inside, helps too. If you don't believe it, lay your hand on the dash while reflective material is in place and then remove it and repeat the dash test an hour or so later. For the sides, awnings are worth their weight in gold.
Try putting your hand between the "reflective material" and the glass and you will find that the heat is transferring through the glass.
Then cover the glass on the outside and you will notice a huge temperature difference.
Awnings on the outside are to keep the sun from directly hitting the glass and heating it up causing transfer to the inside. Its the same reason that shade screens are installed on the exterior of residential windows.
We have made exterior shade screens that attach with magnets to the exterior of every window of our RV and it has made a tremendous difference in the ease of controlling interior temperatures.
