I bought aftermarket OEM tow mirrors from ford, part number ending in DA. I have all the other bells and whistles working (aside from marking lights and power telescoping). I’ve read forscan is the answer for the marking lights, but haven’t been able to find anything about the telescoping...
I live in Alaska and regularly have my truck plugged in, and I have remote started every morning with it still connected. I know quite a few people who do the same so I'd say it's safe.
Just got our topper in on Tuesday and got it installed today. Ordered back in October and was told it wouldn’t be in until February. Leer 100XL with frameless rear window and key fob lock/unlock. Very happy with how it looks.
