Absolutely. Ramchargers have pretty heavy factory inted rear windows, and I will be tinting the front as dark as I can legally go (35% opacity, I believe), when I put in new carpet I added extra heat and noise damping material, and i will be adding extra heat and noise insulating material to the roof, doors, and walls as I go. Believe, i have been fighting keeping my dark blue full size van cool for years. Heat insulation is very important!
