My wife and I have been searching floorpans for a few months now and have narrowed it down to either the Cyclone 4250 or Dutchmen Voltage 4150. We are totally sold on the side patio and need at least 12 1/2 feet of garage length. Ive found plenty of new and a few what looks like gently used units. One of the used units I found only has 2 A/C units. One is in the garage the other in the main area. I currently have a 34' TT with a single air unit and I just don't think a singe unit would be sufficient for a trailer that large. I asked him if it was possible to add the 3rd unit and he has no clue, he doesn't even know if it has the power management system. Does anyone have a 4250 or similar sized Hauler with only 2 A/C units? Any input from anyone that owns a 4250 would be great! Good and bad experiences and what to look for when i go do my inspection.
