I have the same type of cart, but with one set of wheels. I carry a sleeping bag, two person tent, ground pad, sleeping pad, duffle with clothes & personal items and food. I also have a Camelbak BFM with more important gear. Pulls and pushes nice, when I posted about my set up I was asked to try it over really rough ground, I didn't around the yard going over rail road ties rocks etc. Have you tried pulling it through the woods over down trees, large rocks or across a stream etc???
