My dash lights AND parking lights went out at the same time when I hooked up a trailer (that had non working lights). All the lights (dash, parking, headlights) came on but as soon as I opened my door (door lights came on) the dash and parking lights cut out and have not returned

I checked the fuses in the fusebox under the hood but they are fine. I've never had an electrical problem with this truck before. I need to diagnose this problem because not driving at night really sucks! Where do I start?
