I am not sure I could tell a good seal from a bad one both being in brand new condition.
With that said there is an art to using the BB and
not putting too much grease in the hubs. It is a Goldilocks kind of thing. Not too little and not too much.
Another advantage is the hubs are better sealed than with a dust cover. Because the hub is under a very slight pressure and keeps out any foreign things because of that pressure.
The down side is the expense. Because the temp differences are not as great as a boat trailer the temps in a travel trailer temp to ramp up and then ramp down in a duty cycle. In a boat trailer the temp ramps up and then slams down when the trailer is dunked into the water. This system allows for hub protection in far greater temp variations than most travel trailers typical duty. That kind of protection may be a lil over kill, like sending in a cannon to do a rifle job. If you have the cash to burn ($25) go for it.
