Yeah, unfortunately it is a fiberglass camper with a lot of wood in it. The fiberglass shell would be a lot more waterproof if they didn't put in overtime drilling holes in it. The one I ordered from the factory I told them not to put anything on the roof - ladder, racks, antennas, awnings etc. - all of which add maybe 100 holes and potential leaks. Even the hatches and vents can be installed without screws, as have done with any I have resealed. Some joints, like the jack mounts or hand rail mount get worked a lot, you just have to pay attention to them and reseal when necessary.
