I drive a 2007 37 foot Super C diesel with a group that I sing with. I also own a 2016 newer 36 foot Class A gasser. The weight comparison of both rigs is close. Here is the difference. The Super C diesel gets about 10 miles per gallon of fuel where my gasser gets about 6-7. The Super C has more power on hills and takes them at lower RPMS. The only downside to the diesel is that it heats up more on the hills than my gasser. The gasser is louder because of it's requirement to downshift more frequently than the Super C. The diesel is not more sluggish. I would recommend the diesel if the cost is not prohibitive.
