BUYERS BEWARE....DO NOT PURCHASE ANY GULFSTREAM PRODUCT I am writing regarding a New Gulfstream Yellowstone we purchased May of this year (2004) We have a safety issue being: Water in the roof area. We believe this is caused from the layer of Flex-Foil Insulation above the layer of Batt Insulation. This layer of Flex-Foil acts as a Vapor Barrier trapping moisture in the Coach. Gulfstream will not repair this under their warranty, nor will they take any responsibility for this matter at all. Gulfstream tells us we never controlled the moisture even though we have ran a de-humidifier since the date of possession. BUT GET THIS: Gulfstream DID NOT vent the fan avove the cooking area as they claim it is not meant to be vented. Makes sense eh? We also have sewer odors coming from the kitchen sinks and air condition when it is turned on. We have had our unit into the dealer 2x - 7 weeks in total - this is the 8th and nothing has been done to date to resolve these problems. We have contacted the FTC, NTSB and BBB in Canada and the States. No one seems to have any jurisdiction over these RV Manufacturers. They have to be made liable and responsible for the products they manufacture and sell. How many people have to die or be injured before our Governments put a stop to this Ripping off of the Consumers both in Canada and the States? Maybe our roof will fall in from the extra weight of the water up there, we could be seriously injured or killed. Do the Manufacturers of these products care...NO, they just want to sell their units, not warranty them or look after the customer after they do sell a unit to them.
