No it was at my shop. I mis wired a welder plug for the rv. My 50amp plus is 220, and I thought the 3 prong was too, just with a lighter breaker.. WRONG!
but making a driving mistake vs a plug-in mistake.. but they just don't see it my way. I think I will cancel State Farm and seek a different company.
I am not sure what you mean by "making a driving mistake vs a plug-in mistake".
But if you wired a plug incorrectly and then plugged your RV in to it, then I would say that's your fault and not surprising they won't pay the claim. Lots of questions on here about wiring home pedestals and the general consensus is to get an electrician who not only is licensed but familiar with the difference between a welder outlet and one for an RV. As you learned the hard way, there is a difference.
A 50 AMP RV outlet requires 4 wires - 2 hots, a ground - and a 4th wire that is a neutral to split the 240V into 120V. Your RV appliances actually run on 120V. A welder outlet has 3 wires - 2 hots and a ground. So with no neutral to split, you get all 240V.
50-amp RV shore power should REALLY be called a 100-amp service since it does supply 50 + 50 amps, which equals up to 100 amps of current draw but at 120 volts.
