Classic Mopar Use ????

I will admit, we try to plan so that we aren't dealing with the high heat/humidity when we travel. When we went to the Grand Canyon in our '77 Ramcharger, we left the first week in September hoping to at least have cooler evenings. it worked out great. Mostly was in the high 80's in the daytime, but really no humidity, made it very nice going down route 66 with the windows down and wing windows open :)
