I turned my climber into a game cart
 

I just got it the other day. My first impressions are pretty good. I do think that rough terrain and hills will be a problem tho. Level ground it should be great. Great for hunting public areas. Here is my video review.

That's a pretty neat idea. Will it work with a hang on or just the climber. Not any trees straight enough to climb out here lol

I've seen a few models that use only a single tire, above which the load is tied to hang off either side. I would suppose those could traverse rough terrain easier. But this still seems like a cool DIY project.
