I dunno how many mechanics I've talked to about this and they just shake their head.
There is a big difference between how a newer model auto wheel bearing is sealed vs how a trailer wheel bearing is sealed. A trailer bearing is at a far higher risk of moisture & dirt contamination than that of an autos. A bearings longitivtiy is also greatly impacted by the load it carries.
I do not know why the auto mechanics you have talked to would shake their heads as I would think most would know that many/most newer model cars with ABS systems have very well sealed bearings - in fact so well sealed replacing them involves replacing the hub - at a cost of a couple of hundred dollars or more a hub. They are made and designed to go a long time between replacement - many about 100-150,000 miles.
Have had two different friends in the past year or so get stuck in the small towns for 2 days while they wait for FedEx to deliver a much needed trailer wheel bearing and seal to the only repair shop for miles.
When was the last time you heard of someone getting stuck in a small town for days due to an auto wheel bearing failure?
Having had a new wheel bearing failure, carrying an extra set of bearings and seals for the trailer is cheap insurance that I don't end up wasting a couple of days vacation waiting for parts!!
