I have one, but it is a bit noisy to tow when empty, not making it very stealthy. It is a kid cart, built for two. It will handle a deer, or half an elk. It also has a front wheel that will attach, making it a three wheel cart. All wheels are pneumatic, and we got ours at Toys R Us.

I will usually drop it off in a central area I am hunting, then come back for it if we need to haul something out.

I'll try to take a photo or two tomorrow.
