I have a 2000 Viking Saga and have noticed some rot on the floor along one wall. Its about 2' long and 3" wide running from one wheel well toward the front. You can notice a slight dip in the flooring inside the camper. Is there an easy way to replace the rotting wood without removing the camper walls? All I can figure out is I would have to remove the interior cabinets and water tank, pull up the linoleum and remove the flooring from the inside. Can it be done from the bottom?
