I did that with mine. Works great.

Good point about grounding. I somehow never could get an acceptable ground through the hitch to my truck chassis, so I made a short jumper using large gauge wire and clamps like you would have on jumper cables and clamp one end on the trailer and the other end to a good ground point on my truck chassis and I haven't had a problem since.Google is your friend:
Nearly all trailer light problems are due to grounds. I don't agree about wiring where nothing gets wet - its a boat trailer, it is supposed to get wet. Use water proof connections, get something that solves the ground problem, run LEDs.
