That 350 hp Cummins is gonna have about 650 ft/lbs of torque and they have such a flat torque curve that it'll handle that rig just fine.

Ours is a 2011 Berkshire on a 2009 chassis (pre-DEF) and we have no issues with the 340 horse. I would imagine the 350 would have plenty of power for the Berkshire.

In the past we’ve had a 350 Cat and a 425Cummins. With each we pulled a Jeep. The last rig was bigger and heaver but I notice a big difference with the two diesels. With the Cummins we were getting 11 mpg. It we were going back to a Class A I would get the larger engine.

We have a 08 Berkshire with the 350. I haven't had a chance to drive it in the mountains yet, but the few hills that I have climbed with it was rather disappointing. We love the coach, but a larger engine would be nice. We are currently averaging 8.5 to 9 mpg.

We have the 2011 w/ DEF and the 360hp motor.

While I feel the power is adequate, I would stress the need to plan ahead and maintain momentum..

These units accelerate fine, but will bog on the hills if you slow half way up..

I have a 350 hp in my Berkshire and it lacks performance and poor gas mileage. Lucky to get 7. Go with the bigger engine cause I wish I had done so.

Thanks. I'm looking around for a Class A with 400HP and 1000+ ft pounds of Torgue. I'm still looking.

We have a 2011 Berkshire w/DEF. On a recent trip to Williamsburg we averaged 12.6 mpg without towing. Had all the power we needed. We are heading south right after Christmas and will be pulling our Grand Cherokee. I'll let you know what our mpg are while towing.

I'm really not interested in MPG but more the engine level of torque. At 55-65 miles per hour hitting a large uphill grade will it keep its speed or slow down to about 45 Miles per hour before you reach the top. If you have the torgue and good transmission it should be close in maintaining speed. This is just a general question as I know everyones rigs are different. This is why I'm considering the 400 HP diesel with 6 speed Allison transmission. Just gathering facts.
Thanks

Iggy, with the 350 engine you also get the Allison 3000 transmission rather than the 2500. From what I have heard from many on the forums and at Camp Freightliner the different tranny is worth the upgrade. I think if you are looking at getting up into the 400 hp range, you'll probably not be staying with the Berkshire. If that is the case, you may want to check out the Entegra. They're a really nice coach with beefier power plants than the Berkshire.
