A wheel barrow has worked much better than the light weight two wheeled carts on narrow trails and cross country. I think if you could fit a bugger wheel on one it would work pretty well. I keep thinking about chopping up a mountain bike or just removing the front forks but leaving the handles for a DIY game cart.
