wheel maintenance

My r.pod 179 is a bit over a year old...I've pulled it about 5,500 miles. The Lippert axle brochure that came with the trailer says wheel bearings should be repacked at 12,000 miles or 12 months, whichever comes first. The trailer shop in town (not an RV dealer) recommends repacking every 3 years, although they would agree with the 12,000 mile recommendation. Just wondering what others on this forum think/do? I'm planning a trip to AZ this winter (round trip 3,000 miles) and don't want to push my luck. 

We greased the bearings on our 2016 179 after 12,000 miles using the zerk fitting.  A couple of thousand miles later, one of the bearings failed.  4 or 5 hundred miles later I decided to replace the bearings in the other wheel which turned out to be unnecessary. That being said, I wonder about the admonition to visually inspect and pack the bearings.  That's easy enough to do for the outer bearing.  However, it is impossible to inspect and pack the inner bearing without destroying the seal.  My recommendation is to 1) remove and rebuild the hubs every 12,000 miles [cheap insurance] and 2) carry an extra hub, completely assembled along with a grease gun.  At the same time, I have owned vehicles for over 55 years, driven hundreds of thousands of miles with no maintenance whatsoever to the bearings and the only time that I have ever had a problem with bearings was with a properly maintained bearing.

Are there any YouTube videos showing the method for repacking the bearings for the type of hub in the R-Pods?

Sure is a YouTube video!It is from Lippert, so it should be accurate.

Thanks for the link!
