We have only used this trailer one time. Due to unforeseen circumstances, we are selling it. This trailer has always been kept inside a shop. The stove, refrigerator, kitchen sink, shower, and central vac have never been used. We used the heat, but not the air. The awning has never been out and the outside grill is still in the box. We upgraded the AC unit to a low profile Dometic penguin and put a second battery on it. More pictures and information upon request.
