I suggest a torque multiplying wrench - see

I had a brake job to do on a 34' Gulf Stream Scenic Cruiser. This tool worked as well as advertised. The brake job also required replacing a rotor which meant removing a hub and pulling the axle. This tool has a 1" drive - so I purchased a 1" to 3/4" converter and a 3 1/2" (or there about) 6 point socket to remove the axle nut. The tool is small enough to carry with you.
Watch out for left threaded lug nuts. In my case the driver side was left threaded (meaning you turn clockwise to loosen and counter-clockwise to tighten). I learned the hard way, but luckily I only mangled the nuts that mount the decorative chrome wheel cover.
