Is there any difference in DRIVING a gas class A vs diesel?

I had at least 26 different RVs. Somehow I never found the diesel to be more powerful than the gas. The v10s rev up and go like a bat out of hell compared to the cats and Cummins. And even going uphill, the gassers can pick up speed better, and they also have transmission braking.
No, the difference is the chassis. Air ride and rear engine make the difference. Bigger tires, better axles, better steering.
And yes, right now I own 2 RVs, both diesels, cloth Caterpillar.
