Roof seals, window and slide seals & caulking

Thanks ken56 and garyemunson. I really had no idea about caulking and seals being checked every 6 months; if they'd told me that I would have had the dealership check that. The svc mgr asked, "did you specifically request that we check the seals when you brought it in to be winterized?" Well, no, because 1) I didn't know to request that and 2)I had no idea the manufacturer put in caulking that wouldn't last more than a few months. Apparently winterizing is simply draining lines, the water heater and putting antifreeze in. When I take my truck into the dealership to be 'serviced', they check everything that needs to be checked for whatever season--winter or summer. Doesn't it make sense an rv dealership would do the same? Why would you want to sell so many trailers and not help your buyers take care of them properly? The svs mgr, when I told him about the foot-long section of seal missing from the top of the slide, said, "Well, did you check to see that it was there before? Maybe the slide caught on something and the sealant came off." It clearly looks as though the guy at the factory ran out of sealant/caulk and never finished the job, but who can prove that? He said Forest River doesn't take care of their buyers and that the dealership is just the middle man. I'm waiting to hear what their response is. I feel like I should get a new trailer. If I'm not happy with their answer, I may contact our local news station; they have a "Help Me" reporter. Businesses do NOT like to have their poor customer service on the evening news. Especially when there's such competition among the dealerships--we have at least 6 locally.
