Just found some serious frame cracks on both frame rails just to the rear of spring perches. What really irritates me is I just got it de-winterized by Camping World & asked them to check it over closely to be sure it is road ready as I was takin it from Seattle to south Texas. Cracks on both sides were originating from where cross brace attached. Have advised Forest River who manufactures Sandpiper. Waiting to hear if they will stand behind their product with an obvious defect.
