YEARS ago, they made 11k and 8k RV roof AC units. They stopped making them because they did not sell that many. I would stick with Dometic or RVP(Coleman). Other brands are basically orphan units, even Atwood(owned by Dometic). The model listed below is a LOW POWER RVP 13.5 which should do the trick for you. Doug
