I appreciate the warnings, and I'm generally a cautious person. This is not a cross country rig, just a local tootle around for the wife and I. It's an unmodified camper, and the rear end is in really good shape. I even have a rig I could tow it around with if I needed, but it runs well, drives smooth, and I'm currently maintaining it.. I normally travel at 50 mph max, because it's comfortable. I'm not climbing mountains, just driving on the Prairies. Not sure if I will replace the axle or not, but not today.
