Was on my way to CO last year and had driven 400 miles in 98 degree weather. Stopped at Limon, CO and a restaurant before going to the hotel. Was in my '15 Laramie 5.7 towing an ATV on a trailer. Got to go to restaurant and I shut off truck without thinking, forgot I had my dog and immediately hit the starter to leave AC on. No response whatsoever, no click no nothing. Holy sheet, now what. I fiddled around and finally called AAA and had to explain where Limon was. Of course it was a Sunday. Finally tow truck showed up, he lifted hood, immediately jiggled my positive cable and things started right up. Couldn't believe it, I knew to check these things but the cable was on and not displaced. Screwed it down and all was good. Still kick myself.
