Apologies for digressing from the OP topic ... but I'll reply to
prndl. I installed oil bath on a customer's trailer ... shortly after I added it to my fiver. Here's the link to his install. I'm the 4th reply down with a link to the actual job in that reply.

Other thoughts are spelled out in my replies. About one year with oil bath and I LIKE EM! Some say oil bath is not for RV's as they sit and let the oil wick off the bearings. We've had them on farm trailers for years that sit all winter ... not an issue.
