Ok, sold our 3407, but did not like carpet along slide edge. Not fan of Rear Radiator, but had no issues with it, other than it seemed to put out lots of heat into toad. Believe side radiator is more efficient but have no studies to prove. Loved the all-electric part especially, and did not want hydraulic slides period, had issues in last coach with them, but wished it had HWH jacks, better quality on them than equalizer, but again no issues, just never "auto leveled" correctly, always had to do it manually, Newmar checked, "that is the way it is". If we won lottery, would get the 35' New Aire, because of the 460 engines. But it's a "computerized" motorhome, so if computer quits, make sure back up system available, we had one which did not have lots of backups. Also, no perfect floorplan, so some compromise regardless. Sure more, but brain dead now.
