Not sure I can be bothered to go down this route, but having tried the alternatives (including your suggestion) if you plan to regularly move large reds any distance there is nothing else on the market that compares, your plasterers bath does not include a built in blood tray to keep the carcass from sitting in blood, nor does it run efectively on skids, and they are nothing like as strong. As some wise people before me have said, if you can make the same or better for the money then I suggest you compete on the market, as there currently aren't many contenders out there, just a lot of critics.........
