We pull our batteries when the trailer is in storage and keep them on a battery tendor in the garage at home. I think this helps maximize the batteries life and this way I know the are always ready to go. Takes 10 min to remove and place on tendor, little bit of a PIA, but worth it to me.
I dump after each trip, adding water to the black tank if it's not at least 2/3 full after using it on the trip. Occasionally I'll use a bucket to move some grey to the black if my fresh water tanks are getting low.
Hitches are noisy. A little concerning at first, but then you get used to the "expected" noise your particular hitch makes -- especially while turning.
