Driving off with the power plugged in.

Thanks for all the responses everyone. I took a look at the electrical box that the cord runs to inside the RV and it appears as though it pulled the cord out of the housing box, and the power cord near that end is extremely taut.



I'm thinking I should disconnect the battery power and take a look inside it see if the terminals or anything else got damaged. Do I just disconnect the house battery like I would a car battery and then I'm safe to investigate?
