I wouldn't call "preventative or proactive" maintenance "paranoia".
Dirt/dust/mud can act like sand to bearings and over time render your bearings in a less than smooth shape.
Moisture in the air or rain can splash into the now open bearings and that can start rusting the bearing surfaces.
While 5 hrs doesn't seem like much time to worry, we don't know exactly what kind of roads the OP was driving on or if it was raining.
Takes a whole 10-15 minutes to pull the bearings and drums and clean out the old grease and refresh with new grease and once you are done with that you have the satisfaction that you now have prevented a possible future bearing disaster that would leave you on the side of the road ruining your trip.
Besides, it is never a bad thing to routinely remove the drum, inspect the brakes and refresh the grease.. Most axle manufacturers require that to be done every 12 months or 12,000 miles which ever comes first.. Have you ever looked at your brakes? Most folks never look at the brakes let alone refresh the grease.
Not to mention JR is correct, caps do not typically pop off for no reason at all.. Best to investigate.
