Xp1000 Wheel Bearings

How often is everybody replacing the original wheel bearings? I had one go right at 1300 miles on the rear end. (Worst sound i have ever heard by the way.) Got it replaced no problem and was on a gravel road ride this past Monday and lost another one at 1450 miles on the front. Now I’m not saying I have been easy on them, i like to ride in the creek beds (full or empty) so they get wet. But my dad has a can am outlander and it went 5000 miles before losing only one rear wheel bearing. The difference is that it has 2 separate, bearings that, in total, have 4 seals where ours are single, large, bearings with a split in the middle of the inner race basically made for water or mud to enter.

If anybody knows of a 2 bearing setup, I would like to give it a try because i would assume if ive lost 2 bearings, the other 2 are not far behind.
