No Tail Lights?

I have a 99' JGC Limited and was pulling a trailer with 2, 4 wheelers last night, when I started off every light worked perfect, when I got to my destination I realized the trailer lights no longer worked along with the tail lights. (Brake lights work fine) also half of the dash lights went out. I dont know how I didnt notice that when I was driving but anyway, Any help would be great. Thank You

check your fuses, you may have a short in the trailer somewhere that caused you to loose power.
If that is not the problem, check the harness where the trailer lights tap into the wire harness.
