I have rigged a rolling cart for my gear - old injury prevents me from putting too much weight on my right shoulder so backpacks that can hold all my gear are out.
Instead, I found a California Innovations soft-sided cooler with rolling cart. The cart has a 300lb carry limit and weighs less than 1lb. It has big oversized wheels so it can easily roll over tree roots and rocks along dirt packed trails. I removed the cooler and slid on my shoulder bag. Great fit and no worries. Works great everywhere except snow and sand. For snow and sand, I use a sling bag over my left shoulder and limit my gear to one body and 2-3 lenses plus filters. The rest stays in the shoulder bag.
