Tiffin's Allegro Bus comes with a side radiator while the Phaeton comes with a rear radiator. I really like the side radiator. It stays cleaner and it's a whole lot easy to access the engine compartment. The side radiator was one of my "must haves" when looking for a coach. Newmar also runs side radiators on the Dutch Star and Mountain Aire, but not the Kountry Star. I'm pretty sure that all of the 2004 and up Vectras and Horizons are now side radiator also but the Meridian and Journey are still rears.
