RE: Class A Motorhome Engines

As to avoiding a V10, thats kind of silly. The V10 is and has been an excellent motor, and as of a few days ago Ford announced they are going to offering it in the medium truck market as well, territory previously you'd only find a diesel. That would be on account of the price of fuels. Diesel is 40 to 75 cents more per gallon. And the V10 motor has almost the same torque numbers. Well...yes and no. Fuel cost is definately an issue, the torque numbers have a bigger spread. The V10 is 362HP/457TQ in the Commercial Truck segment. The 360HP diesel offered (Cummins ISB) is 800TQ. If you opt for the smallest diesel offered, the 220HP ISB, it comes in at 520TQ. In the consumer Super Duty truck the new 6.7 PowerStroke offers 440HP/860TQ. My '13 PowerStroke is 400HP/800TQ and it's an animal. I don't see me ever going back to a gasser in a work type truck. An F150, sure.

RE: Winne Turbo Diesel or other V10 gas model???

In 1999 Winnebago made the Adventurer on a Ford chassis, a Chevrolet chassis and a Freightliner chassis. The freightliner had a 5.9 liter 275 hp Cummins ISB engine. It also had air suspension. One big drawback was the outside storage. The diesel model had only 95 cu. ft. of outside storage while the Ford and Chevrolet had 162 cu. ft. The freightliner had a GVWR of 23,000 lbs. while the Chevrolet had a 16,500 lb. GVWR, and the Ford had a 20,500 lb. GVWR. The 34' model was the only one with the diesel option. They made both a 35' and a 37' model, but they were only available on Ford chassis. Here's a link to the 1999 Winnebago Adventurer Brochure. http://winnebagoind.com/resources/brochure/1999/99-Adventurer-bro.pdf You might want to check the towing capacity. It might be only 3,500 lbs. Some friends of ours have one with over 200,000 miles on the odometer. They tow a Suzuki Samurai which is a pretty light vehicle.

RE: Which engine for a used Winnebago Journey?

Myself and two of my family members own DP's of the same vintage. All holiday rambler endeavor's 38' in length. Mine and my brother's are both '99 models with the 275HP cummins ISB. My dad's is the C7 CAT with 330HP. I have driven all three. All three perform great. The CAT does have slightly more noticeable power but not a heap more. I like my cummins ISB. It has 660 LB/FT of torque. The power is more than adequate and pulls hills with ease, even heavily loaded. All of ours have the allison 3000 series 6 speed. Great transmissions! Mine gets a hand calculated 9.63 MPG. This is combined flat, in the hills, and quite a bit of generator usage. My dad's with the C7 gets about 7 max. So yes, he has more power, but he gets less mileage. Would I rather have the CAT? Not sure. I do like my fuel mileage better than his, and mine gets me where I need to go with ease. Pick the cleanest rig you can find and don't worry about the engine.

RE: Which engine for a used Winnebago Journey?

The Cummins ISB 5.9 Engine is a good engine and is generally combined with the Allison 2000MH trany. The ISB 275hp (5.9) is a flat land engine when in a coach. the Allison 2000MH tranny is limited to 600FP torque and Banks enhancement would exceed the limits of the tranny. Unless you are exclusively east coast flatlander like me, go with the 375hp Cat.

RE: What to do? Gas/diesel

I have had two P30 chassis class A's. One was an '82 fleetwood southwind 34', the other was a 1994 georgie boy pursuit 28'. The '82 had pretty good power and got about 6mpg. The '94 was LAZY when it came to power. Nowhere near the power of the '82. It also got about 6-7mpg. The heat of the engine and manifolds between the driver and passenger SUCKS. It would literally burn the side of your foot unless you were wearing boots. Fan noise, no exhaust brake, hydraulic brakes and no air ride are all things you'll deal with in a gas coach. I decided to sell the gas and try diesel. Wow, what a difference this is. Engine is now out back. I don't have to hear it or feel the heat. The driving went from white knuckle lumber wagon, to smooth and comfortable two finger driving as others have described. This thing climbs and descends hills with ease. I love the power of the DP and the exhaust brake. The air ride and brakes are the cherry on top. I have one large 13'6" slide that makes it feel like a mansion compared to one without a slide. The deal I found was a 1999 holiday rambler endeavor with the 5.9 275hp cummins ISB. The deal also came with a 2006 honda CRV tow behind, all set up for towing with brakes and the whole setup ready to go. I paid $32k for the whole thing. Oil changes are 17 quarts(less than $75 oil change and that lasts 10-15k miles). Change it once a year and you're good. I also have a 90 gallon fuel tank and onan 7500 quiet diesel generator that can run everything on board all at the same time. All the power you could ever want and it's pretty quiet. I have my RV loaded heavy with all my goodies. And I pull a trailer with all the sand toys that weighs about 6k. All of this and I am pulling down a hand calculated 9.63mpg. Holiday rambler endeavor's get my vote!

RE: 275 hp Cummins

I also have a 5.9 275 cummins ISB in my '99 endeavor. I have been wondering the same thing. I ran into a gentleman at a gas station a few months ago that had a 5.9 cummins in his truck and swore up and down you could put a programmer into an RV with the same engine. He called it a smarty JR and said it cost about $500. He also said that the engine would go from a 275 hp to a 325 hp(or more) with just adding the programmer. Not sure if this is true, but might be worth buying if it actually works.

RE: If you only had $40k to spend.........

Keep your eyes peeled and the deal of a lifetime will come your way. I started looking about this time last year, and by august 2014 the deal I was waiting for came my way. A gentleman wanted to sell his RV and toad together, would not separate them. So I purchased an immaculate 1999 holiday rambler endeavor DP with a 2006 Honda CRV toad for $32k. This was the whole package, towbar, brake system on toad, etc. Good thing I was also in need of a second vehicle!!! Mine has one large slide and air brakes, air ride, 5.9 cummins ISB, 7500 onan quiet diesel generator, all the options. We have used it 6 times since august(mostly week long trips) and we absolutely love it. A dream to own something this nice!

RE: Fleetwood Excursion

I happened to glance at a 2015 Fleetwood Excursion 33D. It has a 300HP Cummins ISB 6.7L diesel engine. The coach I own has a 340HP Workhorse 8.1L gas engine. Both have the Allison 6 speed transmission. I'm no mechanic or engineer, but I can subtract. Would I not be losing 40 horse power? Would that some how be gained back because it is a diesel? Yes because you will be gaining a lot of torque at very low RPM. It would be a night and day difference driving. Not to mention its a pusher so it will be a quieter ride for you with the engine in the back.

RE: What would you buy for a $175,000?

This is only 33' short by 7' of your wish, but what a deal: http://www.happydazerv.com/default.asp?page=xInventoryDetail&id=864742&p=1&vc=class%20a%20diesel&s=Year&d=D&vt=motorhome&fr=xallInventory In case the link doesn't work, it's a 2013 Fleetwood Excursion 33D The only problem is that it is a Cummins ISB-6 which is what is in a pickup truck and non-sleeved. Need to go to an ISC or bigger to get sleeves and more power. It will be a little under powered. but itis a good deal for someone that can over look the engine. Does that mean I need to sell my 42' with the same engine that gets 10mpg and goes down the freeway just fine and up every hill thrown at it? And it still can pull 10,000lbs. Wonder how this forum got so many Cummins engineers on it. And Freightliner should be sued for ordering rigs not capable ( according to some here) of performing as they are pushing the engines too hard. Somewhere along the line the measure of a MH capability is how fast it goes up a hill. For what it's worth the engines (ISB) were in many different platforms before they were ever put in a pickup truck.

RE: Which engine for a used Winnebago Journey?

In similar sized engines like the Cat C-7 vs the ISC, I would take the Cummins. When it comes to the Cat C-7 vs the Cummins ISB, I would definitely by the Cat. It's a well built engine and is definitely more powerful. Just make sure what transmission the two have. The Cat should be mated to the Allison 3000, but the smaller ISB might be mated to the Allison 2500. The Allison 2500 would always be a deal breaker because you can never uprate the power on the engine because the trans is maxed out at torque and HP.

RE: 2007 Monaco Cayman XL 37 pbd ???

"bcforce"....You'll be very disappointed with that coach. Our friends have that EXACT model. Here are the issues. -It has the 4 airbag chassis (Roadmaster R4R)and is VERY rough riding. I worked on our friends and added Koni shocks, adjusted the ride height and brought the air pressure down to the minimum for their weight and the coach is still rough riding. So much so, it knocks the clothes off the rear bedroom closet rod on every trip. -That coach has the recalled trailing arms and they would need to be replaced if it hasn't been done already, about $3500.00. -The 07 Cayman came with the Allison 2500 transmission and Cummins ISB engine. The engine has modest power and will move the coach along well (about 45 mph in the mountains towing a small toad). Typically, if more power is desired, the ISB can be uprated, but in the case of this coach, the transmission is already at it's max. Most savvy buyers will look for the Allison 3000, so upgrades can be made at a later time. -The Cayman, as well as most other Monacos in those years had paint issues. Unless it's been stored inside, the clear coat along the roofline is probably already failing. The 37' was very roomy with the four slides, but I think you'll be disappointed with the all the issues above.

RE: Typical Fuel Mileage You Get With Your Gas or Diesel Class A

300HP Cummins ISB 6.7 Palazzo, 24K lbs 35ft long, 11.6MPG running 63 - 65mph towing Jeep wrangler on pretty flat roads. Going to play with Allison mode button this coming season on a long trip. Heard stories of 13+MPG in that mode... Very unlikely that the Allison transmission in economy mode will give you that kind of MPG. Flat roads= best MPG. Economy mode makes little to no difference on flat roads (i.e. you are in high gear in either mode all the time). Yes, economy mode will aid MPG in rolling hills and mountains, but you will not do better than on flat ground in those conditions. I used my econo mode thinking i was being smart, and then i tried it without it and it was better without it. Not sure why, seemed liked it just changed the shift points, so it didnt kick down as fast climbing hills. Once we hit CO I ended up shifting manually a lot. Using my RPM gauge as a guide as well as my engine display.

And that information did come from another Palazzo owner I know personally and he drove his across the country. Somewhere on the order of 8000 miles last summer. So, he might be telling a fish story, but we will see. His Palazzo is the 33.2. Mine is a tad bit heavier 35.1. Might be plausible with what he's got. But mine, last season's best was 11.6 from NC to Florida on I 95. So yeah, pretty flat! But yeah, 11.6 is not bad considering I had a 6.0 F350 pulling a 40ft 16K lb fiver before this and the best I could squeeze out of that was 8MPG, if I was lucky. 4:30 gears, but it pulled like a scalded dog! :)

RE: Typical Fuel Mileage You Get With Your Gas or Diesel Class A

I have a 2007 chevy 2500HD with a duramax. I used to have a 5th wheel toyhauler and loaded it up with sand toys. I never got more than 9mpg running 65mph. I sold the hauler and bought a gas class A, chevy P30 454 engine. Never got better than 8 pulling a trailer. 9mpg not pulling. Now I have a DP with cummins ISB 5.9 275HP and get about 8mpg pulling a heavy trailer. Not pulling I get about 10, running 65mph.

RE: Slide issues

I'm with Wayne on this. You might want to consider a different chassis in particular with consideration of your desire to tow a heavy vehicle. The Freightliner chassis the Palazzo is built on utilizes a Cummins ISB engine paired with an Allison 2500MH transmission. Although adequate for the size coach the Allison has a gross weight limit of 33,000 Lbs. I don't know how much an empty Palazzo weights but you really don't want to over stress the transmission. Over heat it a few times with a heavy load and you might be facing an expensive rebuild. If you can find a coach within your budget with an ISC version engine and 3000MH transmission I think you might be a bit happier. Just because the builder installed a 10K hitch doesn't mean you are good to that weight. Run the numbers to ensure you will be within all the various limits. I am a bit surprised Thor installed a hitch of that size. Most rigs built on this chassis have a 5K hitch such as a Tiffin Red or a Coachman Cross Country.

RE: Economy mode on an Allison Transmission

We have a 2014 Thor Palazzo with an Allison MH2100 and a Cummins ISB. With the mode switch on and on flat ground with the cruse control set I was able to get 15 MPG. With the mode switch off I was at 12 - 13 MPG.
