I have an 08 with the hemi and tow package and have towed trailers with it since the day I got it. Last night the trailer running lights were working fine when I left the house but 15 minutes later they were out. The brake and turn worked and the vehicle running lights were fine. This morning I checked the contacts with a voltmeter and there is no current. I only found one fuse (20amp #23) in the manual and it appears to be fine. Am I missing a second fuse???


On further inspection I found two relays for trailer lights that appear to be for turn and brake, but I do not know how to check them. And my voltmeter is trashed with a bad battery. So I will get a new one and check again in a couple of days.
