First off, good for you regarding checking and packing the bearings each year. Like you said, it isn't expensive and you can stay on top of things before they go south.
I purchased a 1979 Starcraft tent trailer in 1989 and had it for 17 years. I checked them every year and they were in great shape when it left us in 2005. I repurchased this same trailer in Jan of 2017 for my daughter. It had been neglected and I needed to do quite a bit of refurbishing. When I got to the wheels and bearings, they were just fine and I am very sure that the interim owners did not service them like we had done. As a matter of fact one of the wheels was getting pretty close to being dry. The bearings themselves were good. So, how long do they last? We are going on 39 years with ours.
Of course they were good, 39 years ago we didn't have the junk that is prevalent today. I have had bearings that were defective from new and to answer the question of "how many miles do you get on a set of bearings", my answer would be from zero to God only knows.
