Advice in Trailer Life's RV Clinic

In the ”RV Clinic” section of the September Trailer Life, a reader asks about his E-Z-Lube Dexter hubs. In his response, Jeff Johnson replies, “…there is no manufacturer recommendation for adding grease to those hubs between regular maintenance intervals. According to a Dexter spokesman, those hubs were designed for the marine industry….The Zerk fitting allows the bearing maintenance technician, following the regular 12-month or 12,000-mile inspection and repack, to pump in enough grease to fill the entire void inside the hub with grease. This feature is, of course, not needed for RV trailers, (my emphasis)….” Johnson and the Dexter rep are not discussing “Bearing Buddies.” The article (page 126) is clearly about E-Z Lube hubs.
According to the manufacturer, as of September 2015, they were designed for boat trailers and are not needed on RV trailers. The take-away from this is, according to the Dexter spokesman, bearings should be inspected and repacked 12-mo./12,000 mi. The E-Z Lube fitting is for a bearing packer’s one-time use if servicing a boat trailer.
Now does this jibe with the Dexter manual you got with your trailer? Or is Dexter sending a confusing message?
(Please note: This isn’t a poll asking what you do or why you do it. That topic is a dead horse, several times over.. I want us to share what our understanding of the hub’s use is based on the written evidence in hand.)

Dexter makes the axles, not Trailer Life. I certainly would follow the manufacturer's recommendations not a magazines. And how many travel more than 12,000 miles in a year that would be beyond the Dexter recommended repack/inspect mileage? And if you do travel more than 12,000 miles in a year do a supplemental repack.
