As a fulltimer of almost ten years with a Freightliner XC chassis, IF we upgrade our RV the next one, if a Class A (I'm leaning toward a Super C) will a be side radiator. My reason that any different Class A will not be a rear radiator chassis is simple: ease of maintenance. Easy access to hoses, belts, fuel filters, fan system, water pump, thermostats, injectors, turbo and the like without going through the bedroom floor. Mechanics as a rule "hate" standing on their head to work on engines, you can and will pay for that rear rear radiator in additional labor and interior cleanup.
