Sold my 96 GMC ZR2 a few months ago, auto hubs, 16 years and 266,000 miles on the odo. Hubs never gave me one problem ever. Mostly a daily driver but it did see MANY a nasty trail through the years, and light/medium towing. For me auto hubs is where it's at! I know what you are saying though, my friend tows his bobcats/other loaders to muddy job sites all the time, he has HD manuals, and for good reason. I guess what I'm trying to say is that I would defend auto's 100% unless I was doing that stuff or running a dedicated off-road rig.
