So this is what I think I learned from this post. No difference in HP engine is smaller with 2 valves instead of 3 on class A's in pickup trucks used for TC's. Brakes are the same from 2008 on. MPG is a wash. GVWR is higher for the 450, but in reality storage space for stuff is the same so not a big discriminator. Lower gears in the rear of a 450 allow larger size tires for greater ground clearance for dirt roads. Having spent a small fortune on my IFS front end I would still like to know if either front ends are problematic? I assume they are IFS not straight axles like the class A's is that correct? Fully loaded for travel what would be the approximate weight of 24 ft Class C.
