Class C that's easy to fix?

Just my 2 cents here. Never worked on class A but have heard they are harder to work on (engine bay at least) then class C. Class C is not too bad but more time consuming because you may have to go from dog house inside to outside more. One thing that comes to mind for this discussion, don't think the class C engine bay is that bad once the air cleaner set up is removed as it blocks all access to the front of the engine. (belts, alternator, water pump....) There are very few class C with pick up truck chassis (Scotty Sero comes to mind) and they are very desirable and expensive. like stated on a class C removing the air filter set up make working on the engine much more reasonable
