You know how much I travel with the grady. I always always repack bearings every year and than agian before the ontario trip in the fall. Bearing buddies are fine but if your still looking around get the axles that have the spindle grease fittings, what that does is gets grease to the rear bearing as well as the front. This set up is the balls. bearing buddies only grease the front bearings. Spend the money and get a trailer that is rated more than what you plan on hauling. Sounds like some serious miles you will be going with this trailer. Some marine companys will slide a piece of junk under a boat to keep costs down and get the boat out the door. Some gradys I looked at were set up that way plus they were trashed so junk on junk was the set up. I was lucky to find mine it was excelent shape and the trailer was over rated for the boat..Good luck!
