Cab and Chasis needs bed

I live in upstate NY also your right there are no manufactures here but tons of places that sell and install flatbeds. You may have to do some traveling to get the bed you want installed that is what I did. There is a place in CT. called Trailer Depot that sells CM truck beds you could called them to see what they have. Depending on where you live and how far you want to travel I have a list of body installers I can PM you if you would like or you can call the makers of the bed and they will tell you where their dealers are located. Some of the auto dealers will only work with one place so you may have to do some of your own leg work to find what you want.
