Answer
I personally saw one that uses two wheels in the front, increasing front stability.  I thought that was a pretty good idea.  The gas-driven "power mules" that are basically quad-runners with a front-end bucket looked Cool, but where expensive.  Since I'm a rather big guy, moving them around isn't a problem.  The slighter-built person may really struggle with an over-sized one or one that requires a higher lift for leverage.  I once say an improvised rock mover.  It was just a wheelbarrow with extended arms to increase the amount of lift force on the leverage end of the wheelbarrow.  Maybe consider a side-load or side-empty configuration?  Just an idea.
