It sounds like your trailer has the stubby spindles on it that are usually associated with boat trailers. It is possible that you will need a special dust cap to fit it if there isn't enough space for a standard one (the trailer manufacturer should be able to direct you to the best option). But there is another possible solution. If you can tell me the diameter of the wheel center pilot hole I can see if center cap is available.

There are Bearing Buddies, # BB2047 or # BB2047SS that are slightly larger than 2 inches (2.047 inches) that could potentially work for you. Grease cap diameters are normally slightly larger than the hub bore so that could be another reason why you can't find a standard fit.
