Wide angle lens?

I just bought a 24 foot class C, the rear window is higher than the road and I can't see anything out of the rear window. I have mirrors on both sides but would still like to see out of the rear window. I have seen these squares placed in windows and would like to know if anyone has experience with these as to whether or not they will work.

Although they provide a blurry image of what's back there, they provide a good safety factor for the cost. It's been a number of years since I drove a Class C with one installed; now after having the camera on my current coach , I'd consider installing a camera , if I ever went back to a C.

Easywind, what you're talking about is called a Fresnel Lens. Originally developed for large lighthouses, the principles are now well known and cheaply reproduced in plastic. You can buy fresnel sheets in many sizes, small or large, and it will stick to the glass without adhesive. I have an 8 x 12 on the pax door window to cover that last blind spot-- cost about $7. You could buy a good large one for your rear window for about $30 or so, I would guess. Check on Amazon, they have lots.

The image you see will be a little fuzzy, but will cover the full scope of the back of your MH. Remember, it's a mirror image 30-40 ft away. Detail is unimportant-- you want to see presence and motion, and this will do it for you.

However, as skip and zip said, as inexpensive as they are you might also consider a camera.

Good luck!

I have one on my rear window. Works great when passing to tell when I am clear with the toad. It's natural to use it with the rear view mirror. I have a camera. But use the lens more often because it's automatic to look in rear view mirror.
Here is a link to one.

Thank you everyone. I will be pulling a toad on a tow dolly and I want to make something very clear as it pertains to the answers. I cannot see the road through the rear window, any part of the road. If the image is blurry I really don't care I just want a general feel for what's behind me.
