So I really don't know why we should be worried about doing much more than giving our camper bearings more than a few pumps now and again.
After our 3000 mile trip to Wyoming, two pumps on the grease gun and the "old" grease was already coming out.
But of course, I won't wait until I have 50,000 miles on my camper to remove, clean, and check my camper bearings, but I won't be doing it every year either. Maybe when I figure it has about 10,000 miles, maybe not. Depends on whether or not the bearings begin to need tightening on a more regular basis, which would indicate they are beginning to wear.
For those who don't do their own maintenance, the 10,000 mile mark would probably be a good time to get them checked.
