Greetings AKirby,
Thank you for your reply!
I have Googled this topic before but I didn't find the vendor you shared with me.
I've spent time measuring my stock mirrors for minimum and maximum travel. I called and asked questions of the vendor to make sure I understood how they determined the minimum and maximum travel of their mirrors.
The numbers I have on the BA Boost Auto mirrors when extented add an additional 1.5" out on the drivers side and 2.75" out on the passenger side when compared to my stock Super Duty mirrors. I would call my numbers as plus or minus as I can see the points I measured too may not be the same points measured to by BA Boost Auto.
Also, I had my lovely Bride hold up a mirror along side my stock Super Duty mirror on the passenger side and measured out to find a spot that I can see the front and rear corners of our enclosed trailer. I learned my Ford mirrors need to extend 4" to 6" farther out than I thought and originally posted at the start of this thread. My bad!
Thank you again, AKirby!
I'll keep shopping.
Craig.
