My front cap has been leaking for about a year, and I have had it "repaired" three times already under warranty. It is still leaking, and, in fact, it may be getting worse. This cap contains, among other things, a nearly queen-sized bed for sleeping. I have read on Thor forums that countless other owners are having similar problems, which stems from the front cap not being secured/installed correctly. This includes missing seals and/or missing screws. My fear is that this cap will continue to sag/loosen and eventually fall/break off while I am driving, or while someone is sleeping in this area. This potentially could result in fatalities / loss of human life.
