Aluminum wire - gaack.
My old '52 Spartan is wired with aluminum.
There are several burnt places in the wiring at and around wire
connections.
The solid aluminum conductor house type wire tends to break from the
slight nicks that wire nuts put in the wire, and from the vibration of
towing. There were a couple of breaks that looked like that was the
cause.
RV 120VAC wire really should be stranded like any vehicle wire but the
solid copper house type romex seems to do well enough.
Aluminum is fine for high power wire that is spliced with big honker
clamps that are tightened with wrenches but not good for small gage house
wiring.
I don't trust the water for drinking or cooking. I trust the Everpure
filter to the drinking water spigot a little more.
