Wiring in 5ers

We are considering purchasing a 5er in the near future. Another thread on this forum has raised an important concern. Which manufaturers is any use only stranded wiring, UL approved switches, receptacles, and fixtures?

UL approval is, IM0, self-serving. UL exists on funds receivable from companies requesting UL approval, ie: a company pays to obtain UL approval by funding all testing.
For Alternating Current, no mfgr. uses stranded wires bundled together, instead solid-core wire is used because it is much cheaper to buy, and because outlets and terminals are cheaper to make.
Direct Current wiring, however is always stranded wire.
The RVIA is the equivalent of the NEC for recreational vehicles, and governs electrical wiring.

I wouldn't worry if they are UL listed or not. I would worry about who actually put the unit together.

UL listed

Recreational vehicles are covered in Article 551 of 2008 NEC "national electrical code"
So all 120 volt boxes and receptacles shall be UL listed as all electrical parts must be.

Appreciate the input. As I said, this concern was raised because of a post by another member in another thread. I agree that UL sometimes doesn't mean much, although as I understand it, there is a big difference between UL listed and UL Approved. Sorry, but I don't want Chinese electrical fixtures.
The poster stated that the wiring in boats is all stranded wire. Since they can be hooked up to shore power I can conclude that 120 AC can be runn through stranded wire. For safety sake, one would think that some manufacturer would us it and use it as a sellling point.
