This is what my dealer found after dropping it off. They have turned it into Keystone, so we will see what they say. A 3-month-old camper should not have this problem.
"Rear entry door threshold is not fully scaled in the corners. Water weeps out at times, over the edge if it starts to build up and not drain fast enough out the bottom of the door. The front entry door is not leaking water, the front cargo door and the exterior floor line moulding is leaking. The flooring is excessively water damaged in cargo area. The off door side cargo door leaks also, which is where the major floor damage is. Removed all the customers items out of cargo area and found the vinyl stained and the soft flooring a on the off door side. Found that the off door side bedroom window is not set right either. The front edge of the window, you can see the seal but the back edge is completely compressed into the sidewall of the unit, not making a seal around the edge. Vinyl flooring, trim, and under liniment in cargo area is completely damaged and will need replaced. Mold is forming in flooring as well."
