So, I just got done reading at tfltruck.com that Chevy introduced at the North American Auto show a 1/2 ton Silverado a 3.0 L TD Duramax inline 6 cycl. mated to a 10 Speed auto tranny and doing in excess of 30MPG. Got to believe that. I think that is the same motor Isuzu/Chevy/GMC uses in the cabover commercial del trucks, so why can't this motor pull a B+ motor home of 12,000 GVWR down the road. It would certainly be stronger than the V-6 TD that the Sprinter uses on their RV chassis!
The Isuzu NPR motors are inline 4s. The 3L would be fine in a motorhome application but at 150 hp and 282 ft/lbs torque performance would lag behind the Transit or Sprinter. The NPR HD uses a bigger engine (5.2L inline 4) with 210/452 that would outperform either one but you're looking at a much bigger, heavier engine.
