330 has 950 ft lbs torque, the 350 has 1050. That does make a difference as does adding the Banks, although on a 330 it doesn't give you all that adding it to a 350 does. Does bring it up to 420 HP and 1125 ft lbs though.

Sometime with the exhaust brake on; it will shift down hard and show a (2), but all other time it shows (6) no matter what the trans is actually in. The full filters are new, I've had to change them often due to algea in fuel tank. Have treated the fuel hope to be done with fuel problems soon. The MH runs down the road great no problems. I'm just not sure how to use the Trans to be most efficient in climbing hills from stop.

Does your transmission pad have two readouts or one?
If just one then it is showing the pre-selected gear, not the actual gear. If you have two read-outs then one will show the pre-selected gear and one will show the actual gear.
From what you describe I assume you have one read-out so when you see 6 the transmission will be trying to get to that gear, but the load on the engine will prevent it from actually getting there when going up a steep grade. If you hit the down arrow, the preselect will only take you to the preselected gear (5th, 4th, etc.).
Your engine brake is usually set to pre-select 2nd gear. As your coach slows and as RPM drop, it will shift to the next lowest gear and if no throttle is applied it will eventually go to 2nd.
What you need to do is preselect a lower gear (start with 5th) when going up a hill. If it stll feels very sluggish then go to 4th gear via the down arrow. Don't expect to get the same performance as when driving in the flat lands.
Going down hill, just turn on the exhaust brake. If you slow too much then use the up arrow for a higher speed. If you don't use the exhaust brake the rule of thumb is to descend in the same gear you used to climb the hill, or one lower (assuming you used the proper gear going up for good performance).
Driving this way will accomplish the same thing as monitoring RPMs, etc., but is much easier to do if you are not really familiar with those factors.

Close, but no cigar.
Econo Mode, or Mode, does nothing for fuel economy on flat lands. It does improve fuel economy on rolling hills.

The only time Econo Mode changes anything is if the engine/transmission is shifting gears. So that would only be while driving in town, accelarating onto the highway or climbing hills. (you should not be in E Mode for steep grades). On low power diesel motors it is recommended not even to use E Mode if towing a vehicle. How much you can use E Mode is dependent on the power of the motor and the total weight of the MH.

IMHO The ISB 5.9L Cummins is a great workhorse but is light on the torque side. An engine with 300HP and 1200lbs/ft of torque will outhaul an engine with 425HP and 800lbs/ft of torque. I suspect the 5.9 will put out around 900lbs/ft torque, whereas the 8.3L Cummins consistantly puts out over 1000lbs/ft at all HP ratings (longer stroke crank in the 8.3) I have vehicles with both the 5.9 and the 8.3. My choice would be the 8.3 for any motorhome. Thats my 2c worth. Hope this helps.

I have a Mercedes 360hp with 1000lbs of torque and regularly pass 400hp and 450hp as we climb any steep grade....

Not true, the 330 has 950 ft lbs. Not sure about the 300 as I don't have an output curve on it, but it won't be any higher than 950.
