Water logged 2003 Starcraft Antigua

Sounds easy enough. I will do that today along with scrubbing the inside with bleach and water. I brought a wood strengthener yesterday and hope to apply that do the areas that are not rotted. So far I only have to replace one section near the dinette. I was thinking of placing a sheet of plywood over the hole dinette area. I know it will be a different height but it should not be that cumbersome since it is not in a walkway. Another stupid question, can you plug a 30 amp into household plugs with an adapter or will it fry the electrical system? I have a dehumidifier and fan running with an extension cord now but would like to plug directly in so I can completely close the unit for drying.
