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

We just traded up from a 34' Fleetwood Bounder with the V10 on the F53 chassis to a Fleetwood Discovery 39'pusher.
The air brakes took a little while to get used to but the ride with air suspension is in my opinion much smoother than our gasser.
I think a lot has to do with the weight of the coach.
We loved our Bounder and took her cross country with never a hiccup even on long mountain pulls.
Looking forward to many great adventures with our new rig.
