I have used Hagan mirrors on many projects and I have never been disappointed with their quality or function. On my 41 PU I am building I added Hagans peep mirrors atop the doors. You have to commit to these as they do not clamp on, the door must be drilled. But because of it they are very sturdy and do not intrude into the jamb. Hagan uses convex glass for a better view of your surroundings. I also purchased an interior rear-view mirror. You purchase the mirror heads separate from the arms and mounting fitments for a custom fit. Not cheap, likely the most expensive mirror on the market but safety first. I had to laugh at that last comment I made since I see in the picture my welder and a gas can sharing the same space.
