We bought a 2009 Oak Creek 18 X 80 from the Tulsa location and we have had nothing but problems with it every since! We have had problems with eveything from the electricity to the ceilings to the hot water heater. It has been very difficult to get them to come out and work on the house at all and when they do some of the work they do is very unsatisfactory. Our house is a very poor quality home and Oak Creek refuses to do anything to make this right. And their 7 year warrenty is a joke. If you are looking at buying a house I would not recommend Oak Creek. Their customer service is almost as bad as the quality they put into their houses.
