I bought an early Cabela's Super Mag Hauler with the metal spokes and those spokes were terrible. They caught lots of grass and brush and came loose. I even carried a spoke wrench for a year before I rebuilt it with 21" motocross rims and tires. Those were too tall and heavy with brake drums. I had an old wheel chair, so those lighter nylon wheels and narrow solid tires are on it now and much better. Actually I prefer a heavy sled with holes for rope tie downs. It slides well over grass and snow and the center of gravity is much lower. That sled pulled with my Rokon has been my preferred method lately.
Back when I hunted with a back pack, I did mount one of the small wheel chair wheels to the bottom of my pack frame. That way I didn't need to go back to get the hauler when I quartered one up. I could wheel a load out like a wheelbarrow if I got tired of the weight on my back.
