Cody I hope things ars getting better fir you. I have a good friend in Livingston Parish that is fighting the flood.
Regarding your power issue I would unplug and not reconnect until your are positive it is correct. The important question now is if the dryer outlet is for 3 prong or 4. You need 4 for 50 amp RV service. You MUST have a neutral wire and a 3 wire dryer circuit does contain a neutral.
