I went to Martin Glass to see if they could put a custom piece of Lexan on the back of my truck where the truck topper was missing the back window. They could and more! I was leaving on Saturday to drive to Chicago and then on to Oregon, where I'd be moving. I stopped by on Thursday and we agreed to work Saturday on the truck. hey offered such incredible service that I would highly recommend them to anyone. Over the course of fitting the piece of Lexan, they consistently advised me on the best way to fasten the hinges and lock the Lexan--just like a truck topper back. Since I was driving across the country (Chicago to Eugene, OR), I was hoping that the Lexan would keep the rain out of the truck bed, though, reasonably, I didn't actually expect it to because it's just a piece of Lexan on the back of a truck, not a real door. However, it kept the rain out the whole way! Thank you Martin Glass for the best customer service I've had in years.
