I have the same problem on my 27. I have 3 inch peep mirrors and they are better than nothing, but barely. I am going to add a center mirror on the windshield, Dan put one on his rpu and he said it makes all the difference in the world. My 23 had some nice 4 inch mirrors that worked well, but I don't know what they were off of, I bought them with some other parts off of Ebay. I think they were motorcycle items.
