What is your oil pressure gauge doing? Low oil pressue will cause lifter sound. Check your oil. A small exhaust leak will sound like lifters also, but generally will go away after the exh manifolds heat up, if they have a small crack.

It has rusted threw. Replace the filler tube or use silicone to plug the hole. Not to much though, you don't want to plug that line. It is a vent.

I would suspect the light switch is bad, can you hear the relay click when you turn the lights on? If you can't, replace the light switch. Check for voltage at the light bulbs, if you have 12 volts, replace the bulbs.

It's a very good possibility that it is the trailer. You say that it is new, is it a brand new trailer or just new to you? If it is brand new, and you bought it from a place that deals with trailers, then I would say take it back and have them look over everything. If that's not an option, then it's time to pull out the circuit tester and start checking wires. See if you are getting power to the Blue wire on the trailer, and if so is there power all the way to the brakes. You will need someone to push on the brake pedal while checking the wires. If the power is good all the way to the brakes, then you will need to pull the drums and inspect the brake shoes for wear, and condition of the the brake components. If this is a used trailer, then it would be a good idea to do this anyway so that you can also inspect and grease the bearings. If everything looks good, then the brakes might just need to be adjusted via the slot on the back side of the brake housing. If no power is seen in the blue wire, check the Red wire (12v Aux/charging), if it doesn't have power, then you more than likely have a Ground issue. This can easily be checked by hooking the trailer to the truck (hitch). Both use a chassis ground, and will use the hitch itself as the ground connection, though it is not a good idea to use it as the ground point.
