I would agree on checking the truck fuses. Many vehicles have a fuse just for the trailer running lights. This is so not all of the light functions aren't out and can still be used during daylight hours.
If a ground was bad, then there would be issues of the signal lights not working as well as all lights are usually grounded to the trailer frame. This scenario indicates a fuse.
Now...if you find the fuse is bad, you replace it and the fuse goes out again, then that is a sign of chaffing happening on your running light wires somewhere, creating a short in the system. I had this happen on an old shoreland'r trailer and kept blowing fuses in the truck. Ended up pulling lines on the trailer to find the problem and fix it. Not the most fun process, but it is doable...
