I have no spectacular range to tell here in the Pacific Northwest with my Av.
HOWEVER - when I owned by Pontiac Montana and used it for travel writing my adventures brought me to:
Texas, Oklahoma, Kansas, Missouri, Nebraska, Iowa, South Dakota, Colorado, Minnesota, Wyoming, Montana, Utah, New Mexico, California, Arizona, Oregon, Washington, and Idaho in little more than three years.
Record high - Marble Canyon, Arizona - 113 degrees. Man I will never forget that place. The wind must of been blowing at 20 MPH. It felt like you were standing in front of a furnace when you stepped out of the van. Walking 100 feet from an air conditioned store to the air conditioned van a candy bar I purchased melted!
Record low - North Sioux City, South Dakota - -17 degrees below zero. Won't forget that one either. The air was dense and cold it felt almost liquid, hard to describe. Driving the fan with the heat on full blast required me to scrape the ice off from the INSIDE of the glass.
