Not sure why wheel bearings in cars and pickups are usually good for at the very least 50,000 miles, yet we consider repacking the RV wheel bearings as low as every 5000 miles. Lack of use in the off season maybe? But wouldn't everything stay coated with grease and not corrode even if sitting all winter?

In addition, the bearing/race "technology" is the same technology that was incorporated on the 1950 Chevrolet B210 sedan. Cars and trucks have advanced "leaps and bounds" since 1950, but with the exception of the metal alloys used, your trailer bearings are essentially the same "high tech engineering" as the front wheel bearings in your grandfather's (or great grandfather's) old Chevy "tudor" with the wool seat covers. Back then, wheelbearings were packed annually or every 12,000 miles and failure rates were much greater than most of us care to remember.
You simply can't compare the wheel bearings on a modern vehicle to the "old type bearings" on a travel trailer.
