My buddy uses the redneck engineering hitch for his Otter lodge. Use enough rope, slide a suitable piece of 1 1/4 PVC (4 feet is good) over it and tow. Sure, it wants to articulate a bit if you stop real fast but it's surprisingly effective. And cheap. And easy.
Not saying it's the best permanent solution but in a pinch or if you're not motivated or budget challenged it works.
