Ford V10 Power, effectivity

Since this seems to be the primary gas engine for motorhomes, and all applications are the same engine and power. Is there a general consensus on coach weigh where the engine no longer seems acceptable, and most people would wish they went with the diesel engine coach?

I know its subjective, and depends on the hills typically driven and we can all learn to accept the slow lane :). It just surprised me that all of these different weight coaches have the same engine.

I admit I often wonder the same as your asking.I see 31ft 2 slide V10 gas units and there ok for power(do the job) and then u see 39Ft 3-4 slide units with the identical engine. I know the late late to new units have extremely low gear ratios and 6 speed trans and this helps a great deal in the heavy ended units powered by the V10
I personally would not want a 38ft gasser in the western rockies but probable ok back east or mid west plains
