I spliced the damaged wires back together at the campground before departing for home. Everything works except the auxiliary and tail lights (which I believe to be the brown wire). Power brakes, brake lights, turn signals all work. Also, all lights work on my TV, no issues there.

My question is there some hidden fuse that I could have blown when the cable was damaged? Maybe the wire shorted out on the power or ground?? I looked underneath but saw no fuse, or any other cable damage.

Thanks in advance!
I did the same thing a few years back in the North Woods,,,
After splicing all the wires back together,,, I found a blown fuse under the hood of our F-150 !!! We went to the nearest FORD dealer and had it replaced,,, I carry a lot of extra fuses with me,,, but did not have that one !!!

Look in your truck manual for the fuse location. The Silverado has a listing what each fuse does and where to find it. My fuse box was under the hood.

Junction Box

I wired a new plug inside my truck box (// to existing bumper plug") for my 5er cable that now hangs down directly into the box.......I also replaced the metal junction box up under the 5er hitch with a "plastic" electrical box.....Original cable got caught and pulled it out shorting the 12v and caused arking and burnt wiring......New wiring connections are soldered and taped--no wiring connectors to come loose.. This is a common fault in the wiring....bare wires just twisted together with marrets.....come apart..J

Forest River method: twist each pair of wires together (sometimes that means 4 wires) and wire nut them.
Junction box method: crimp/solder on a ring terminal on each wire and run trailer wire in one side of post and connector cable in other side of post. All rather neat, tidy, and easy to replace cable if ever needed.
I am liking that!

Mine is under the pin box and jam packed with wires. REAL pain in the back trying to track down an "open" because my battery would not charge. (Turned out it was a corroded connection at the "truck to battery current limiter")

Happy to feed your mod work queue as you have mine (and I *hate* going on roofs but that is where the A/C is so...).

Yeah *that* would be a sneaky little circuit breaker and the version on my bumper tow TT had umpteen wires all connected on this side or that side.

I generally prefer circuit breakers to NOT self reset, to have a visible sign of being tripped, and maybe to have a trip test feature. I hate these little box breakers as they fail my visibility test. Something like this is much better:
