A bit big but it works great.
This is a fully galvanized commercial trailer I use for hauling large lawn tractors and the like. The box on the front of the trailer is usually full of gardening and turf management equipment. As this box locks it great for chucking all the bike gear, tools, spares and extra fuel/oil in there when going on long trips. I've only ever hauled the bikes long distance once but the trailer gets used heaps on the weekend for the trail bikes. It's low deck allows a bike to get pushed on quite easily and there are plenty of tie down points around the rails. I even mounted a couple of loop bolts in the floor of the deck to assist with securing the bikes. The trailer can carry three bikes, no problem.
