The decision is probably made by the coach manufacturer rather that the chassis builder. The decision is mostly driven by the price point that they are trying to hit. Allison 2500 is cheaper than Allison 3000, therefore they can shave the price of the coach. You get what you pay for!

FWIW. Our former '08 40 Ft coach had an ISC 360. Our Current '15 42 Ft coach has a 450 HP ISL. The bigger '15 coach consistently gets .5 to 1 MPG better mileage than the '08, running 3 - 5 MPH faster on interstate HWYs. The GVW of the '08 was 32,000 lbs, the '15 (tag axle) is 44,000 lbs. I attribute the mpg gain to the improvements in engine tuning that can be done with a DEF engine.

Not quite so. They will do "Service" work on any Tiffin coach, no matter the age or warranty status. I regularly see 10, 15 and even 20 year coaches in the service bays when I go there for service. They do NOT do "renovations or modifications" to coaches. There are a number of businessmen in Red Bay, former Tiffin employees, who make a good living doing mods and upgrades and their work is excellent. They take appointments and will accept 3rd party warranties. Tiffin doesn't do appointments because too many owners abused the system by making appointments a year in advance, and then no showing. They stopped doing 3rd party warranty work because they were having to devote 3 fulltime staffers to collecting from the warranty companies. Carl, maybe you should verify your information, especially something that is so far out in left field, before you post that info. All you would have had to do is say "I heard that........... Any truth to it?"

Just exactly what do you base this statement on! If this were the case, then the folks on TRVN would be reporting it, and they aren't. The only things that they aren't doing anymore is making appointments and honoring third party warranty's due to the fact that they were having too much trouble getting the warranty companies to pay.

Pretty sure that Jayco owns Entegra.

The wobble issue is a Cherokee issue only, not a Grand Cherokee issue. They are two Completely different designs. The Cherokee is a front wheel drive platform (Fiat I believe) modified to become a Cherokee, with 4WD or all wheel drive if ordered that way. Still a transverse mounted engine/transaxle design with a takeoff to drive the rear wheels when necessary. The Grand Cherokee is a traditional front engine rear drive or 4WD based on the Mercedes Benz ML SUV series.

Yep and Yep. I heard that they applied a "fix" to some Grands, which caused the Transfer Case to fail. Tried to fix with hardware. Our '12 was never updated and we never had any problems. (Until the lightning)

The "Death Wobble" is with Jeep Cherokees, not Grand Cherokees! They are two completely different vehicles. The Cherokee is a Jeep/Fiat developed unit using many Fiat components including a transverse mounted engine (read front wheel drive/all wheel drive), the Grand Cherokee is a Jeep/ Mercedes Benz development which shares many components with MB SUVs. No Problems with "Wobble". As far as the Transfer case is concerned, we had a 2012 Grand and towed it for 30K miles with no issues, until lightening got it! (Fried computers)

It's called an Air Admittance Valve (AAV). Get a Studor Mini Vent at Home Depot, $22 - 24. If you have multiple sinks with P-traps, you might should replace them all as the RV manufacturers seem to use the cheapest ones that they can find!

I suspect that the aluminum foil will suffer the same fate as the nest if I crank the engine without removing it. I'll pick it up on my pre-departure walk-a-round. BTW, I didn't know that there were younguns it the nest until it came out. The nest was mostly around a bend in the pipe. They wouldn't have survived anyhow. They were just hatched, and we will be driving in less than two weeks.

I found a nest with baby birds in it in the exhaust pipe of my coach yesterday. Cranking the engine evicted them. I now have the pipe plugged with a wad of aluminum foil.

The Tiffin owner"s " manual" is in fact a big blue bag which contains not only a generic "owners manual" for the Phaeton, in your case, but also a copy of the documentation for every system that is on your coach, including but not limited to, A/C, heaters, Refrigerator, Microwave, TV's, Jacks, generator, chassis (Freightliner or Spartan) tires, and more. It's a huge pile of paper. The previous owner should have left it with the coach!

The only downside that I know of is if the campground's wiring to the 30 amp pedestal will not support 40 - 50 amps consistently and overheats. This can burn the inside of the pedestal, as well as cause issues for other campers who are on the same circuit from the CG's main distribution system. I used one for years on my previous coach. (2008 DP). My current coach has a smart load sharing EMS which won't allow the use of more than 30 amps if it cannot sense a real 50 amp connection. You can get one of the adapters at Camping World.

My coach, with a Cummins ISL 450 uses about a gallon of DEF every 310 miles. I have averaged 7.1 MPG since new on this coach. This usage does include generator fuel usage, so the actual miles per gallon of DEF is probably a little higher.

Never seen DEF pumps on both sides of a truck lane. Also, never seen DEF in the RV lanes, although I avoid the RV lanes at FJ for many of the reasons stated earlier. Only go in RV lanes when that's where the Propane fillup is.

There are class action lawsuits happening against Navistar because of these engines. They were an attempt to do emission control by EGR only and not use Urea injection like Cummins does. The attempt was a failure and is costing Navistar a bunch of money.

FWIW. If you accumulate 20,000 points in a given membership year (Renewal date to renewal date) KOA extends your Value Card for another year at no charge.

Tiffinrvnetwork.com will give you more information than you can stand, both the good and the bad. TRVN is NOT run by or supported by the Tiffin company, just a bunch of Tiffin owners!

I suspect that Wranglers break more than other vehicles is because their owners "Torture" them much more than owners of other vehicles. People buy Wranglers to go places where you wouldn't want to take your average SUV, not to mention regular automobiles. I have owned 8 Jeeps since 1985, 3 old style Cherokees, a Liberty, two Grand Cherokees, and two Wranglers. I don't believe that any of them were any less reliable than the other cars, vans and SUVs that we have owned. Our current Wrangler Unlimited Rubicon is great, with no trouble since purchase, and it has been "wheeling" more than once.

We want the Two Holer because the older we get, the more often the "urge" strikes us both at the same time!

We love our current coach! Our perspective comes from living in a DP fulltime since 2007, first a 40 footer with 4 slides, 1 bath one sofa, a recliner with computer desk, and two tv's. Now we are in a 42 footer (Phaeton 42LH if you are interested) with a bath and 1/2 bath, L shaped sofa, entertainment center with 42" tv across from it, outside TV, fireplace, heated tile floors, etc. Much prefer the 42 footer. It lives like it is 1 1/2 times larger than the 40! Oh yes, 450HP engine, tag axle, 3 A/C units and a 10 KW generator. Having said that, if we had a S & B residence and only traveled part time, we would probably have something in the 32-36 foot size with much less stuff to keep up with, maybe even, gasp, a gasser!

So if I read your post and signature correctly, you traded a 2011 Tiffin for a 2010 AMC Tradition in 2013. Means your current coach was 3-4 years old when you got it, since the 2010 model year coaches are usually released in mid 2009. This of course means that you got a coach that a previous owner had worked the bugs out of. (Or it means that you rolled the dice and got a new on that had been sitting on a dealers lot for 3 years.) This is not a bad plan if you don't want to deal with "new coach" issues and don't want the latest features found on new coaches, We determined that the features found on the 2015 Phaeton were worth dealing with the "new coach" issues. And yes. our 2015 went back to Red Bay several times during its first year. (September 2014 build). If I were to sell it now, the next buyer would get a basically bug free coach. Most of the issues that we had to deal with were problems with Coleman, Spyder Controls, Attwood, etc systems. Since our coach is one of the first of a complete redesign of the Phaeton product line, we had a few build issues which Tiffin fixed very quickly. We never had to wait more than 5 days to get into service, even during "snowbird" season. We are fortunate that we pass by Red Bay several times a year on our way West or East. We have all of our service work done in Red Bay, but not necessarily at the Tiffin service facility. Sorry you got a problem coach, there is not a manufacturer out there that doesn't have one of these occasionally.

If you go back and read my post you will see that I was referring to making appointments with the "Businessmen" in Red Bay, Brannon Hutchinson, Bruce Deaton, etc, not the Tiffin Service center!

Tiffin made appointments by opening appointments for the year on Jan 1 of that year. They made 3 appointments per working day. Getting one of those appointments was similar to getting a reservation for a campsite that would hold a 40ft DP in the Yosemite NP. People made appointments "just in case" they might need one, and a large number went unused. The other side of that was arriving appointments would push back folks who had been waiting to get in, which caused hard feelings. They tried making appointments on a quarterly basis, with pretty much the same result. You can't please everyone, although Bob Tiffin tries. So now no appointments. They are doing a much better job of managing the service process with express (3 Hour) bays, mobile techs who come to your campsite, and giving priority to coaches in warranty. I made several warranty trips to Red Bay in my current coach and never had to wait over 5 days, even during "Snowbird" season. (Spring and Fall) There are a number of businessmen in Red Bay who do a great job of servicing Tiffin coaches and at a lower labor rate. You get the benefit of being in Red Bay with access to Tiffin's parts bay plus you can, and should, make an appointment. That's what I do for all non warranty work.
