Thanks to all!! This is great information!! The winters in Tulsa are severe enough at times to warrant heat and I have a line on a recirculating heater. By the way, I did not mention it but the VIN number has an L in it which codes out to Los Angeles. No need for a heater out there. I bought the truck from a guy in Yakima WA. It belonged to his uncle who had to move there due to age issues, may have been why a heater was installed. He passed away years ago and it has just sat in the garge for a long time. I should have a post to the Gallery soon!
Here are the photos.
