If I was looking for another big coach, I would be looking at 500+ hp models!

Ben, So why would you put the money into the coach with the bigger engine? How would that impact your use and enjoyment of your coach?

This is our ten year plan so we want to make the best call first rather than two step it. At same time, we have no need to be seen as king of the hill. We don't want to foolishly spend money.BUT we do want to put ourselves in a great position to enjoy the hills!

I look forward to learning from your experience.

Where I live, I'm crossing 2, 3 or more mountain ranges, anywhere I go.
Up here in B.C Canada, many are 8 or 9% grades! My current coach, towing a compact car weighs in at 40,000 lbs. I get up every hill with it's 400hp, but given the choice, I wouldn't mind climbing them a little faster.

Really kind of simple: make your choice and pay you money. There is no right or wrong answer. I liked my rig and engine to push it came as part of the deal. From the factory you had three choices, CAT 625 with CAT trans, Cummins ISX in either 600 or 650. After that the chassis was the same, options were the same, etc.

Great Thread, lots of great DP experence displayed

My better half and I have done some 10,000lb towing with an under powered engine and wrong rear end ratio for the task. Had to pull at over 75 to stay in the power band of the little 1995 G20 350cc Chevy and she only got about 5 mpg on a good day. We had an awesome zero deductible universal warranty so we ran her hard without fear and she never failed.

Sure wish I had a Big Block or Diesel back then, there is no replacement for displacement as we always hear in the racing world.

Now we are looking for a 38 to 45 Beaver DP and I don't want to have to wish that we had gotten a bigger engine. Pretty sure I'll be happy with a C12 with at least 425HP & 1,200 torque on a 98 to 02 Coach.

Our goal is to have a reliable engine that has enough power to not be overwork. We wont have the peace of mind with a warranty like we had with the old Chevy Van.

We've had both now, a 2010 spec ISL 450 (1250 ft lbs of torque) in our 2011 Revolution and the ISX 600 (1950 ft lbs of torque) in our London Aire.

Fuel mileage is almost identical. Right out of the box I was getting 7 plus MPG with the London Aire (it took me 15 - 20k miles to break 7 mpg with the Revolution). The only negatives so far (excluding cost of acquisition) are the DEF use is 2 or 3 times what it had been on the ISL and the regular service cost me about 30% more than I'd averaged on the Rev.

It's the 700 lbs of extra torque that are doing the work, horsepower is just a measure of how fast it can accomplish that work. I had no real complaints with the 450 but there is a marked positive difference driving the 600.

In fact the 37 should be a real rocket and qualify as king of the hill.
Ya, but the 37 is really 39'.

I have a 400hp/1200tq ISL in my 39'11" Itasca Ellipse 32,500 GVW coach. I find it to be from adequate to impressive depending on the situation. I would surely be bummed if I had a similar size coach with a 360/800 ISB. It's one of the main reasons I bought an 8 year old coach versus a brand new Winnebago Forza 38G, same dimensions but equipped with a 340/660 ISB.

I view HP/Torque as a safety factor. It's why I opt for the highest output on any rig I buy. Cars, trucks, boats, whatever. More is better.
