I've used the stick-on Fresnel lenses before on my class B's. Not bad, but I much prefer the backup camera that I installed on my Tiger. It's up high, right under the center clearance light, and is aimed down so the view starts right at the rear bumper to give a useful view when backing. I've added fisheye mirrors to the side mirrors. That makes them fine for driving, but I had a 1/2 million mile rehearsal in my misspent youth driving blind to the rear pickups for a courier outfit. I can see out the back window of my CX in the center mirror, but rarely find it useful.
BTW, Diplostrat, _nifty_ unit!!! Hope you enjoy it in years to come as much as I have my old CX!
