I had an 04 Winne Journey 36g with a 350hp Cat. Power to weight ratio was pretty good. I ended up putting a TST programmer on it and a free flowing exhaust, had plenty of power for me towing. I now have a 40' Vectra with a Cummins ISL, the coach is heavier than the 36' and I feel like the power to weight ratio is about the same. With the ISL it will do 55-60 towing my 20' trailer through the Sierras from Sacramento to Reno NV. The ISL is a good motor as is the ISC. The ISC has a little less hp and torque but not by much. Either will be adequate in a 40' coach. Several manufacturers used to make 40' coaches with bigger engines but I haven't seen any new 40' coaches available with anything bigger than an isl. Monaco, Foretravel and Country Coach come to mind as builders who put larger than ISL motors in 40' coaches. I would love to find a reasonably priced 07 40' Dynasty on Holiday Rambler with the Detroit Diesel 60 series with a tag. Found one last year but the owner knew what he had and wanted way to much $. I personally would not buy a 40' coach with an ISB but there are plenty of people who have them and get to where they are going just fine. They do get better mileage than the ISL coaches and on flat ground where you spend most of your time it does not matter if you have the ISB or ISL. on flat ground I would prefer the ISB for the mileage bonus. Maybe Cummins could take a page from the auto makers and shut down a couple cylinders when they aren't needed.

I went from an 06 Sun Voyager 36' w the vortex (which I really liked) for gas motor, then bought 06 Winnebago Journey w/6.7 Cummins. The power wasn't bad, wasn't awesome, but not bad. The best part was the fuel mileage. 8.5 towing, 9.5 without towing.

Most any RV will get to the top of a steep grade. The lower power units will get to the top, just a bit slower and huffing and puffing more.

More power will get you to the top ant 40mph or more rather than 25 or 30 mph.

It's not all about HP. 340 in a small Cummins (5.9/6.7) will not do nearly as well as a little more HP but in an 8.3 or 8.9.

While I enjoy the power our rig has at the end of the day you'll still arrive at the campground just fine with less HP/Torque.

We have the ISB 360hp/800tq in our Tuscany 34st. Ours does fine but I wouldn't want any less power. The 340hp/700tq with a Allison 2500 in a 40'er is weak in my opinion.

I'm not sure why the big rush to get to the top of the mountain. On the way up is where the most beautiful scenery is. That's a time to slow down and smell the roses anyway. Going down the mountain requires all of your attention to keep the speed under control. A smaller engine just automatically helps you to enjoy it more than the big boys that like to race to the top.

The suggested rule is 10hp per foot. You are underpowered and it will annoy you.

Not a big deal to you with 450 hp 1250 tq.

In relationship to his rig imagine your rig with 360 hp and 800 tq. Forget the mountain just everyday driving is an effort.

I had a 40' Phaeton for eight years with a 330 hp Cat with 860 lbs of torque. We towed a 6300# Avalanche. I never had a problem getting over mountains, albeit slower, and ran 62-65 mph all day long. Our current coach weighs 40,000# loaded plus a 12,000# trailer that we tow. So this rig weighs close to 48% more than the Phaeton w/Avalanche and I now have 45% more torque. That's pretty close to the same power to weight ratio. Would I like 600 hp? Sure, who wouldn't. Do I need it for safe travel? Absolutely not. I wouldn't choose the coach that the OP is looking at, but for other reasons than power.

Only reply I can give is my friend has a 2014 Sportcoach. The linoleum floor would bubble up going down the road. The dealer tried for 8 months to fix it and they finally had to send it back to Coachmen. I don't remember what they did to fix it, but they finally did.
My first reaction when he told me was linoleum?

I love our Mirada and we have had very few problems with it but for a DP I would not buy a Coachmen.

FWIW, before our 03 Phaeton with the 330 Cat, we had a 1999 Bounder 39Z diesel with one slide. It had a Cummings 5.9 with 275 hp and 660# of torque. We towed a Chrysler mini van with that and it had the Allison 545 4 speed transmission. It took us up over Wolf Creek Pass in CO just fine. It got between 9.5 and 11 mpg. Before that we had a 36' Discovery (no slide)with a 5.9 Cummings with 230 hp and 600# of torque. We towed a Saturn with it. My point is that they will all get you up over the big hill to wherever you are going. Some just a little easier and maybe faster.
