Okay, I am in the South and we are experiencing frigid temperatures with snow and ice. Usually we do not have weather like this, but we got lucky- NOT! Anyway, I am impressed with my Ram 1500 DT Big Horn. She is starting up in temperatures of -12 (0 degrees with wind chill) without any problems. I use the remote start from my house and she starts purring as soon as I hit the remote. I was afraid with temperatures this cold, I would have issues. I read on this forum where a member was having starting issues in the cold but I believe it turned out to be a weak battery. This is the first Ram I have owned- I traded a Ford F-150 for this Ram and will never look back- very impressed. The Ram 1500 is an awesome truck!!
