Maybe I'm missing something here, but my first reaction is, "that's crazy!" I am thinking back to the Winnebago MH my parents bought in 1971. It had a 360 V8 with, I believe, 255 HP and 360 lb-ft torque. Traveling into strong headwinds, Dad had trouble maintaining 50 MPH with that beast, and he said over and over he wished he'd bought something with more power. Sure, it was a carbureted gasser, but HP is HP and torque is torque. That gasser had way more guts than this 4 cylinder TD. I cannot see how that diesel will do the job, even if the new units are somewhat more aerodynamic.
