The only difficulty we have had with the 340 is when we were going to Branson, MO. There are some pretty long hills to climb coming into Branson and I didn't get up enough speed coming down the one side and then had to slow down pretty well going up the other side. I don't think I would have had that problem with the 360. The aluminum wheels are intended to get rid of the wheel liners which can be a pain when checking air pressure on the tires and they can sometimes squeak which is annoying.

Larger 360hp with the Allison 3000 transmission.

I doubt the bigger motor is much faster than the standard - so it is
Probably about how much you are going to pull.

I have the 360hp and get around 10 - 11 mpg. I think this might
Be more due to the DEF which was suppose to also help with mileage.

We have 2 seat belts is in the dinette and 3 o the sofa bed. There's are none on the love seat.

I would not say the sofa or love seat are comfy - but are acceptable.
Both seem a bit upright for me. I think I may be
Doing something wrong with the sofa back - but haven't figured out
What yet..

Good luck!

Thank you very much , your milage is impressive , do you know what was the extra charge for that package (motor wheel and transmission)

thanks for your time !

I believe the extra charge for the package was around $15k - but am not positive

This was for the 360hp motor, tranny and aluminum wheels.

I thin 9 - 11 mpg is about normal for the Berkshire. Really +/ a 1 or 2 mpg is not going to matter one way or another. How you drive is prba le going to influence this more than any other factor.

As for the comment on the power helping when loosing momentum - I woul stress that big RVs are all about momentum!! One thing I find annoying is getting cut off by a allow moving car going up hill and having to slow way down. You just can't make up the speed..

Good thread.

I'm looking at purchasing a 390BH but i'm concerned with the power difference there might be between the 340 and the 360.

Any 340 owners that feel there unit is not up to the task of say going over Loveland Pass outside of Denver?

Thanks for any feedback
