Just bought an old sail box from Pete Begle, which I am giving some TLC. The problem I have is that the crossmembers on my trailer are far enough apart that there is no support where the middle of the box would be. I can buy some square tubing and have it welded to the trailer, but I thought I'd see if any of the creative folks here might have a cheaper or easier suggestion to accomplish this. It's a sail box, so there's not gonna be a ton of weight inside, but the box won't last long even empty, with no center support.
thanks
