The Dodge Van-based MH's called "Class C" are the Subject of our attention to Engines V-8 (273/318/360/400/413/440), and Mostly Dual-Wheel Rear Axle chassis, with a A-727 "Loadflite" Version of the "Torkflite" Chrysler Automatic Transmission. Of course, there is a Heavier Frame that is suitable for the "Class A" Dodge-based MH's. Many of the components of the Drivetrain, including Brakes, Engine,and Electrical Systems are shared between the various Models.
I have been studying the possible Upgrades for much of the Standard Equipment applicable to Dodge MH's. For example, I have developed a Cooling System for the front Disc Brake Rotors, when the benefits of air-cooling are compromised by operating in Slow Traffic. I have also developed a Super Heavy-Duty Back-Up Lighting System, for those situations After Dark.
