That trailer is prob 800-1200lbs empty. Bring a spare tire and bring a spare hub kit if you can get one. I tow alot of boats and the bearings go out in them often but thats because they get dipped in water. Its not as big of a problem with utility trailers, but I would still bring the hub kit if I had it.

Keep your speed down, don't tailgate, if it rains slow down even more. If the trailer starts swaying YOUR GOING TOO FAST, let of the gas easy and slow back down.
