After spending the better part of the day scooting around under our 3055 with the slides extended, I think I have found what may be part of the wet floor problems. Under the entertainment slide out, there is a portion of the frame where the black plastic material, that they use to warp the entire frame before they start to install the floor, is exposed. This material was full of cracks. Some as long as a foot. The stuff seems to be similar to the material used in the plastic tarps that they sell for covering boats. We have a sailboat that I cover with this stuff. It has to be replaced every year. It just doesn't hold up long, it too cracks and separates but it's cheap. Looks like heartland really cut a corner here. Patched ours up with some duct tape. Should last for a while. Now that I know causes it I guess I can fix it every once in a while. It's really no fun owning something that cost so much that is built so poorly.
