Larger wire does not hurt PWM system
It's just that it provides no gain in a fixed location RV install over smaller wire
PWM controller will output at it's set voltage, and anything over that is just not used 18v or 16v it doesn't matter, it will pass thru the incoming amps at the voltage set point 13.6~14.4 the extra higher 3~4 volts is simply not used,
So it makes no difference to PWM what in coming is as long as it is above the set point
On the other hand MPPT will take the extra voltage and covert it to extra watts aka amps, and attempt to use and covert every erg of power it can
So any voltage saved , not lost in line drop, is extra amps into the battery
In a portable system, MPPT might be a wasted expense
A long run of wire to put the panel in the sun might result in enough voltage drop that there is little to recover with the MPPT controller vs the PWM unless you go with really large wire , which adds even more expense
