I'd pull them within the first year of the trailer being manufactured and replace whatever the manufacturer puts in them with a high quality synthetic grease. After that I typically need to get into the hub for some other reason before the grease goes bad.
On my truck I seem to get the rotors off every 3-5 years for either ball joints or rotors or something, and that always comes along with a bearing repack. Never any signs of wear on the bearings.
I believe it depends more on mileage than age. In cases like that, I'll typically run increased mileage between checks. Maybe try 10k miles and see what you find. If everything is great check it again in 12k and see how they look. You'll find a reasonable service interval through trial and error.
