RV 50 amp is only 120v OMG

[CUDA]

I just got this diesel pusher from a neighbor getting divorced, I wanted to hook it up RIGHT without any adapters ...

I have a 50 amp welding receptacle in the back building so why is the welder 3 wire the RV 4 come to find out RVs are two 120v lines NO 240v ? sure glad I did not get creative

Amazon 50amp RV box next day service and cheap

When I was 16-18 I worked for a electrical supply and large Industrial electrical motor rebuilder Industrial motors service

I thought I knew wire.

Where is good ol Electric John when you need him?
The reason your welder is only 3 wire is because you don't need the neutral (white) wire for welding. For any 120v load you need the neutral.
