Even if you can't or don't know how to replace wheel bearings on the trailer, it is still a good idea to carry a set of inner and outer bearings with seals. My wife has been complaining about all the "stuff" I carry, and when we lost the bearings in Laredo, and I pulled out the bearings and the tools to replace them, she has changed her mind, especially after we were back on the road in a couple of hours. Of course you should also have all the various lubes needed for the rig, and I don't think a good torque wrench was mentioned yet.
