I'm thinking about building a grain trailer for my feed- something to hold 500-1000 pounds, so I didn't have bags sitting all over my garage, and didn't have to haul, load and unload bags. I was thinking about building a grain box out of 3/4 inch plywood and mounting it on a trailer frame. Would that work? How much reinforcement would you need to put on plywood to hold up to 1000 pounds? Is there a better option? I can't weld. Is there a formula to figure out what the dimensions would need to be?
