I know I have been looking at the options, especially with our 1 year old in a rear facing seat. I think I am going to pick up some foam board from Home Depot and try to make a liner fist, and if it doesn't work then I will buy one and paint the top of the top either white or silver to reflect some of the heat.
At the moment in stop and go traffic or if the Jeep has been sitting for a hile I feel like the top is cooking my brains.
