Cheyenne Camping Center Sold a Lemon, Will not work for resolution walcott Iowa!!. I bought a Flagstaff 620 st two weeks ago and have not even had it out once. Multiple problems with this new unit. Cannot raise unit fully. Water tank was leaking, Screen door was bowed out it would not latch, Could not install screen door because camper will not raise fully. Interior lights do not work–etc. tell me this is not a lemon, it apparently was not gone through with their quality department.
