Sounds like you're well prepared and yeah, replacing a bearing on the side of the road wouldn't be nice at all, but sometimes things happen and it's best to have the bits available...have you put some surgical gloves in your kit also? Will make cleaning up after wheel bearing change easier.
Yes, I actually do carry gloves like that around with me, but only because I use them when I emptying the black and gray tanks after we pull up camp. When I clean, inspect, and repack the bearings each Spring I don't usually wear gloves I feel like they just get in the way sometimes.
I figured you would and for the reasons you mention (I do the same) but I'm not a fan of bearing grease so I use them for that as well. Never had to do it on the road though.
