6 gauge and that's pushing it. At full load, you'd have a 10 volt drop.

That's for Cu; for Al it would be closer to 12V which is what most
places would offer for USE triplex. I just tried to get #6 triplex Cu
at the local supplier (there's only one in small market town) and they
didn't even stock it.

Of course, pulling the full 50A is probably quite unlikely, but
depending on what are the loads, max of 3% is pretty-much recommended
for stuff with motors; efficiency suffers pretty heavily beyond that and
if there's anything with harder starting, may be iffy...

Holy-moly - will he ever get near full load ?
I'd never have guessed that an RV needed a 50 amp service -
- during power outages I'll run my whole house on my
5000 watt portable generator - the 230 volt receptacle on the
generator is labeled 18.8 amps.

He said plug for RV, so I was assuming it's a plug and cord.

Agree. He should analyze the actual loads.

Â* You might be surprised . Those bigger units can have washer and dryer
hookups , 220V AC , etc . Our 25 footer is all 110 and has a dual power
refrigerator (gas or electric) and water heater . Space heaters if you
choose those over the gas furnace draw around 15 amps too . My camper
calls for a 30 amp breaker .
