Curious if others have drain holes through the bottom of their trailers floor? My new 5.0 has one each side behind the fenders and one in the rear middle at the bumper hitch. They go into the cabinets of the dinette and I presume the middle one is thru and under the raised dinnette floor. They were sealed at one time but appear to have been opened up at the factory. There are other holes under the trailer as well but the other ones I have found so far are sealed.
