Freeish trailer 40-1/2 in x 48 in Utility Trailer

My Brother is giving me access to Freeish trailer 40-1/2 in x 48 in Utility Trailer. It’s old but American made, new tires and hubs. Right now it’s bare, I had to add lights and wood or metal to put the kart on. Has anyone used such a small trailer for a kart? if so do you have pictures for inspiration?
