On a Ford V10 F53 chassis you’re essentially sitting above the motor which makes the noise such that it’s harder to have conversations. Lots of RPM too compared to diesel plus most pushers have air suspension supplementing their springs to soften the ride. Dramatically higher maintenance costs can be partially offset by getting side radiator so you can do much of it yourself. Big advantage of the diesel is engine brakes, with a good two stage brake you’ll barely use the brake on those long downhill stretches.
