Question on Trailor maintenance?

[bax]

I live in Maine so I am getting ready to put my boat up for the winter.
Was thinking this would be a good time to do any maintenance to the trailor that might be needed. There is no visible issues with the trailor. I have a 2005 procraft 185 and the trailor is the original that came with the boat. No trailor brakes.
Any thoughts of things I should be looking at/for if anything??
Thanks

I think he only areas you need to be concerned with maintenance wise, is to make sure the lights work, the wiring is in good shape and check/re-pack the bearings periodically.

That is what I thought but wanted to make sure.
Thanks again
