Small Class C - Mercedes Diesel vs. Chevy Gasoline?

Pnichols.. I hate saying this as a Ford guy. But I do not care about all the tech mechanical stuff. All I know from first hand experience is the Chevy chassis is wonderful in cross winds, big rigs passing, getting into the house from the driver’s seat and no noise up front when going up hills. All that done with a stock chassis.
I spent over a grand on my Ford E350 chassis and never came close to the ride I have now.
