Clayton Homes review: Poor quality

Purchased home in Marshall, Tx. Had a few issues during the first year. Major issue was with HVAC unit location. Unit is located in one end of home. It does not provide enough volume to far end of home - third bedroom. Clayton remedy was to add an additional vent. The remedy did not provide any additional volume. They promote energy efficiency however, it isn't energy efficient to have to add auxiliary heat and air to the third bedroom. Additionally, during the second year, the drawers, cabinets, entry door lock sets all have fallen apart. The windows began to poor water during a small rain shower. There is no assistance from Clayton. It is a very poor quality home. I am a long-time home owner and understand home maintenance. Leaking windows, as these leak, are not a lack of maintenance but a lack of quality control.
