I will look into those Jacking Rails. I had a 2014 Fusion prior to this Edge and it had the same jacking setup as this edge so the company probably does have a set that would fit.
Salt is the bane of our existence here in northern Vermont. The road crews start putting it down with the first snow fall, usually in November and don't stop until about the first of April. I'm about 15 miles to the nearest car wash so always figured the car would be coated with salt by the time I get home. Should've done it regardless. Oh, I also had a 2005 F150, by 2015 I had had the frame welded three times due to rust through.
