I agree with the others - Newer trailers are generally rated assuming you are carrying water, and in my opinion most state parks & national parks don't have adequate hookups - so probably good to do so.
Being over a pounds isn't going to break an axle, it's more important to watch your capacity of the tow vehicle. I wouldn't dramatically exceed the cargo capacity, but you don't have to weigh everything as it goes on board either.
