Almost all Newmar's with the exception of the Ventana have a side radiator. Tiffin products are side radiator with the exception of the Phaton. Some of the older Winnebagos (Ultimate Advantage/Freedom) were built on Spartan chassis and have a side radiator. When looking at Monaco/Holiday Rambler/Beaver if it's built on an RR8 or RR10 it will have an "S" at the end if it has a side radiator. I'm a gear head and love my rear Rad. Rarely do I have to remove the dog house panel to work on anything in the engine compartment.
