I know someone who drives a truck and trailer for a living and he also agreed that oil filled bearing would be terrible on a RV unless it is used all the time. His trucking company always has issues of no oil in the bearings if they try to use a trailer that hasn't been used in awhile.
Oil filled hubs have been around for 40+ years on commercial vehicles with minimal issues. The fleets I worked for had trailers set for extended periods of time and the hubs remained full. Maybe we had better maintenance. I preferred working on a oil filled hub over having to pack a bearing set with grease. JMO
