who has 340-hp Cummins 6.7 turbo 2500 Allison

I am looking at the new Winnebago Forza, see if anyone has the same engine, and want to know if this is a reliable engine, how about the speed and torque if GCWR is 33000lbs, GVWR is 27910lbs.

Our sig coach has the Cummins ISB 6.7 and Allison 2500. We are at about the same weights and flat tow our Jeep Grand Cherokee. It's not a rocket ship but the combination goes down the road without problems. We seem to be averaging right at 10mpg running at 65. It will loose some when the wind blows or if we are doing a lot of climbing. It never gets below 50 even on the steepest hills.

The 6.7 has proven to be very reliable. I wouldn't worry about that power train at all.
As for performance, it's all up to the individuals perspective. More torque will always get you down the road better and for 33000# I would prefer a Cummins C series engine but the the 6.7 will do the job.
