Ok, I just checked over all the illumination lights on the front and rear, including wires and bulbs. Didn't see anything. I looked at the trailer wires and electrical taped all the places that I think needs reinforcement. Popped in a 20 amp fuse to the #1 slot (the one that kept blowing yesterday). All lights came on. Replace the 20 amp with a 10 amp. Everything seemed to be back to normal now. I will drive this thing and see if the problem comes back. I have plans to take it to the mountain in the middle of November. Hope it will be ok.

Thanks for the suggestion.
