As a full time living in a home made truck camper, I carry lots of tools, and it came to a point we had to invest in a cargo trailer, so we got a used, only used twice, American Hauler Air-Lite cargo,...

Looked at your video. Yes, that is really bad workmanship. The drilled holes should have been reamed to remove burrs and a grommet installed where wires were run through any steel. The under-trailer wiring is fairly typical in that, most mfgs don't use a loom covering to pull wires from tail end lights to the front. When I maintained a fleet of heavily used trailers, I used garden hose to cover wires as it was cheap and nearly indestructible.
Tips: While you are upgrading, it would make sense to build in a fused terminal strip towards the front of the trailer. They are not that expensive and will ease diagnosis/protect against future problems. Yes, your truck has fuse protection for those circuits but it is often easier having it on the trailer.
If you are connecting/disconnecting this trailer frequently, it may behoove you to use a 7 pin connection to the trailer and break that out on the trailer rather than using a 7->4 adapter. The 7 pin Bargmann connector is vastly superior to a 4 pin.
Good luck with your trailer. The American Hauler brand is one of the cheapest out there so you may be doing more repair/maintenance in the future.
