HELP!!! I am driving from Chicago to Phoenix in a few weeks and planning my route - driving through the mountains seems to be not a great idea this time of year but concerned about the leg between ABQ and Gallup with my 75D. I drove it this summer int he opposite direction and made it but not with a lot of battery to spare. If I go on the SC website it says no problem to make it from ABQ to Gallup but if I put ABQ to Scottsdale it sends me up to Denver and all the way back down. HELP!!! Anyone with experience in the winter driving this route in a 75D or less??
