In mid-May our Dometic furnace and a/c conditioner stopped working. Many cold days/nights without warmth and many hot days/nights without cooling (continue to this day with 100 degree heat in the trailer and we are an 80 yo male and a 75 yo female). We have a Dometic service company working on a solution but to no avail. This is our residence. We can't get relief.Don't buy D away User's recommendation: Don't buy anything Dometic or from Camping World !!!!!
