I'm thinking about finding/building a flat bed for my truck. I was thinking about getting a newer truck, but then I second thought about doing that and instead building a bed for it and buying a nicer car to save a little on gas. Would it be feasable to build a flat bed for a truck like this? After I got my car it would only be used for pulling the trailer and landscaping once in a while. Who's done it before? How much does it cost to build/have built a bed for a truck?
