Bearing should certainly last longer than yours have. You have had front and rear ones go out twice with a different axle and installed by different people. Nobody else is having this problem. I would be looking at what is different about your camper. Your weight is over by a tiny percentage. That is nothing. Are your tires wearing the same? Are the bearings being over tightened or under tightened? What is the difference in your camper?
