RE: Need help with diesel pusher selection

Missed the Newmarket when I was making my list. Ventana and Dutch Star have some good floor plans in 37' range. This brings up another question. How does the Cummins ISB compare to the ISL. I have the understanding the ISB was designed for pickups and light trucks. Should it be straining to get its power when the ISL is loafing? I have a 340 ISC now and am happy with it but would like more torque in mountains.

RE: Gas or DP

One thing to keep in mind is a short gas MH with 362 HP and weights 16,000 lbs will have a higher HP/wt ratio than a 300 or 340 HP DP that is closer to 30,000 lbs. Gas MH's have the same engine whether it is 28 ft or 38 ft. DP's HP go up as the length and weight go up. True, with possibly one *. In the diesel world torque is the better number to look at. There is a big difference between a Cummins ISB rated at 300HP/600# torque and a Cummins ISC rated at 300HP/950 # torque. HP sells stuff, torque is what gets the work done. Seeing as the new Ford V10 is rated at 320HP/460# torque and the lowest rated ISB today has 660# torque, it's something that needs to be considered. With that said, I'd still lean towards a diesel, there are just too many other benefits other than the engine. I would lean towards a DP if I wanted 40 ft MH but in the shorter sizes they are hard to find. Saw a nice winabago 32t with a 350 HP engine but it had no pass thru storage. The CC allures and Intrigues are nice but they are hard to find. I don't want to start a torque vs HP debate but from a pure performance stand point I don't think a MH that weighs 30,000 lbs with 300 HP will out perform a 15,000 lb MH that has 362 HP. The gas engine may sound like it is going to come apart at 4500 RPMs and the diesal is just chugging along at 1400 RPMs but that is all in the design. The increased torque may be better from a stand still but if each approaches a hill at 40 mpg I think the one with the highest HP/ WT ratio will be at the top sooner.

RE: Hubby says we need more power!!

Be careful with that one. According to the 2003 Neptune Brochure you have the Cummins ISB Low Torque engine rated at 275HP/600 lb/ft torque mated to an Allison MH2000 transmission. Looking at the Allison Specs shows your transmission is rated for 300HP MAX with 780 lb/ft torque MAX. HP wise you're close to the limit, and seeing as HP is a calculated number using torque and RPM, you really don't have a lot of room to play with that set up. Bottom line - if you really want more power it might be time to start looking for a MH with a bigger engine and heavier transmission. Am I helpful? :B :h Are you helpful? Probably not, but, you are correct! Chum lee

RE: Hubby says we need more power!!

Thank you all for your input, we really appreciate it! After reading some of the comments to him he said, tell them I'm not trying to do a wheelie, just wanting to get a little extra power LOL! He's tired of going up inclines that are not steep, with his foot to the floor and only going 45 MPG! :) like I suggest get this done http://shop.bankspower.com/i-1124-63754-powerpack-bundle-complete-power-system-with-banks-idash-5-inch-monitor-for-use-with-2003-2007-cummins-isb-commonrail-pusher-motorhome-with-allison-2000.html?ref=category:82 Rear-wheel best gains of +85 hp and +203 lb-ft

RE: Hubby says we need more power!!

We have a 2003 Holiday Rambler Neptune pulling a Jeep Wrangler. The hubby is frustrated with the lack of power that it has when we are pulling on to highways and wanted to know if there are any add-ons to boost the power??? We purchased this unit last fall as our first Class A and would like some guidance from the veterans! Get this installed will be glad u did http://shop.bankspower.com/i-1124-63754-powerpack-bundle-complete-power-system-with-banks-idash-5-inch-monitor-for-use-with-2003-2007-cummins-isb-commonrail-pusher-motorhome-with-allison-2000.html?ref=category:82 Rear-wheel best gains of +85 hp and +203 lb-ft JUST make sure its the 2003 common rail and not a 2002 engine!!!!!!!!!!

We purchased this unit last fall as our first Class A and would like some guidance from the veterans! a diesel pusher loaded and towing with the 300 Cummins is a dog for sure;; I assume its a ISC? if it is here a cheap add on that will maybe get you going good enough http://www.usdieselchips.com/ts-2110301 Not an ISC - as noted above the low torque ISB rated at 275 HP - 600 # tq with the Allison MH2000. There really isn't much extra available to work with until everything is maxed out. yes I was strictly going by OP whom said 300 cummins so I said IF its a ISC try this now once I look its a is a ISB 300HP motor this is what the op needs to buy and install http://shop.bankspower.com/i-1124-63754-powerpack-bundle-complete-power-system-with-banks-idash-5-inch-monitor-for-use-with-2003-2007-cummins-isb-commonrail-pusher-motorhome-with-allison-2000.html?ref=category:82 Rear-wheel best gains of +85 hp and +203 lb-ft JUST make sure its the 2003 common rail and not a 2002 engine!!!!!!!!!!

RE: Serpentine Belt for Cummins ISB 6.7L?

I am looking to purchase a spare serpentine belt for my 2009 Winnebago Journey 34Y that has a Cummins ISB 6.7L CM2150 (350hp) rear pusher Diesel engine. I can't find the part model number in any of my owners manuals. Can anyone assist with this and where I can purchase one? Thank you If you're sitting still for a bit, remove your old one and take it to Napa. Keep your old one for the spare and one you know that will fit. Most likely you'll never need it anyway. Never carry a new spare that's never been installed and with assuming that it will fit properly.

cummins isb engine will not shut down

Upon returning home in our 1999 Winnebago Adventurer when I turned the key switch off the 24 valve Cummins turbo-diesel would not shut down. Had to disconnect main engine harness to stop engine. Anyone ever had this problem?

RE: Looking for Class similar to Winnebago 34y (2009-2012

As said above, The Meridian is the Journey's sister so it might widen your search. I see 3 available on RVT that fit your search. If you go to winnebagoind.com and select "resources", you can get brochures by year and model. This will give you the specs. You can also download the chassis information from the columns on the right. For instance the 2012 34Y had the 340hp Cummins ISB and Allison 2500 and as stated above, a very lean GCWR of 33,000 lbs. To tow over a 5,100 lb trailer would really eat into your cargo capacity. Any of the larger models (36M, 40U, 42E) put you up into the Allison 3,000 and a full 10,000 lb tow capacity beyond your gross vehicle weight, and the 36M is only 36'8".

RE: Replacing chassis battery with group 27 batteries

Let's See New alternator, new isolator You drive, then it won't start, You start generator and then it starts Shut off engine and it won't restart, with out generator Providing it started find, before the new parts where installed I would guess that something is wired wrong If the reason for the new parts was the starting problem Then I would have the battery tested A new 8d will be stronger than any pair of group 27s Although my 5.9 Cummins isb uses 2 grp27 batteries for the engine/chassis

RE: 2005 Monaco Dynasty vs 2007 Fleetwood Discovery

I would agree with Busskipper. What you didn't say, was haveyou personally looked at them? If so then I would think you would have seen a difference in quality, as I feel the Dynasty is a much higher end coach both in build and materials. Are the engines the same, the Dynasty will likely have an ISL Cummins, so compare engine models as a Cummins ISB or ISC will not be as good as the ISL. ISL has more hp and torque. As a retired truck driver with over 3 million miles, that engine should be good for 500,000 miles. Lots of trucks are doing that + and work much harder than any MH will. Price is an ask price, however to me seems in the ball park, just needs to deal on it. Dynasty's were a high end coach and offered many levels. My opinion would be to deal on the Monaco.

RE: Source Eng Fan ISC330

I put one on my Cummins ISB and noticed no difference at all. Its not worth the money as far as I'm concerned.

RE: Jake Brake

And to add to the confusion our 2002 Itasca Horizon with the 5.9 Cummins ISB, the switch is labeled "Engine Brake" but is in fact an Exhaust brake. Because most people do NOT know, or care to know, the difference between the two. Here is what matters....OFF: vehicle will coast, no cool sound. ON: Vehicle is "held"..cool GRRRRRRRR sound. kleenex, zerox, crock pot, jet ski, Jacuzzi, etc.... If it goes GRRRRRRRRRRRRRRRRRRRRR it has a JAKE BRAKE. You might add that some (engine brakes) are extremely noisy (by comparison to exhaust brakes) and why you see so many near village signs prohibiting this cool sound. As for the above nicknames, they describe products that are virtually the same, whereas an engine brake, differs dramatically from a compression brake. As for people caring, they care plenty, when pricing the difference of having the two installed.
