OK, I can admit this here... . We're all friends, right?
I went to look at spots to mount mine. I took it out of the box and went out to the truck and tried a few different spots, but liked the lower left side-- Accessible, but out of the way... Gee why doesn't EVERYBODY mount them here? I'm a genious.
Some time later after the job was done, I went to go someplace. I started the truck which was normally parked in the garage, but because I wanted to mount this, was in the driveway. (better light and space) Driveway was (moved since) a pretty steep hill, so I release the (rarely used) parking brake, and POW, the pedal is smacking my brake controller. DOHHH! The old mount is still screwed to the lower left dash, perhaps as a monument to my stupidity.
