I think we’ve wondered into the weeds. This thread is more about the Coach (shell) than the engine that drives them. Meaning you can have a great floor plan made with good materials and not be a diesel. A gas coach maxes out at 38’ where a DP with tag axle stretches out to 45’. And you don’t see a 45’ gasser because a gas engine is not made to handle that kind of weight. Let’s try to stay in our lane. :)
And MPG and torque and how to eat pork, although interesting, isn’t the intent of this thread. So come out of you corners and shake hands.
