i have a stock 97' f-150 extended cab. I was planning on putting a 3" body lift on it and 275/70/16 bf goodwrich all-terrains. I began to think that maybe once i raised the body there would be a hole underneath the body and you could see trough to the other side.Is there a way to fix this. any information on how a 3" body would affect this is needed. thanks.
