Purchase advice '04 - '06 Dynasty

Hi all,
I am looking at purchasing an 04-06 Dynasty 38' or 40', 3 or 4 slides. Have there been any issues I should be looking out for? Have there been any issues with the tag axle? Is there an option to be sure to get, etc?

Thanks, Byron
(thought I would ask since you are the people who really know!)

The Dynasty is a great coach. The only issue that I'm aware of in that age range is with the Cummins ISL. A known block of serial numbers had the possibility of a defect with a wrist pin which could cause major engine damage. This is a known issue and Cummins will give you the range of serial numbers that could be involved. If an engine is outside that range of numbers then there is no issue.

Just look for a well maintained coach with fresh tires?

We have an 04 coach and I agree with Steve, finding out what the coach has had done for maintenance is very important. Walk around both looking for signs of repainting, branch scratches which are deep, open all doors looking at how they close and fit, look in the engine compartment for hard weathering and check under the coach for anything that looks out of the norm, ie. leaking shocks. Check the tire date codes if newer tires to confirm when they were actually made and then begin to look inside for where there may be signs of cover up. These are just a few ideas, if you let us know more amount what you are looking at (mileage, floor plan models and specs) we could suggest a few more things to look for.

We do very much enjoy our 04 coach, bought it with 43K, it now has 61K, runs great.

Byron, I agree. The Dynasty is a great coach. Monaco increased the interior ceiling height from 79" to 82" in 2005 and again in 2007.
I would look for a coach that as Aqua Hot and make sure it has had the updates.

If you decide to include the 42' models, they will have a 3rd A/C and a larger 10k generator. This may be important if you live in the southwest.

Most of the older Splendid washer/dryer combo's were not vented and many folks complain the dryer portion does not work well. You can replace it with one of the new vented units from Camping World for about $1100.

Steve was right about checking the tires. They will cost aprox $800 each X 8 to replace.

Check the transmission dipstick for the yellow Allison Transynd tag. This is the newer synthetic trans fluid and is very expensive if it hasn't already been converted.

If it has the residential refrigerator that is a big plus. If not, you can convert it for about $2k. Most folks complain the original Norcolds do not cool well.

They come with 4 kitchen chairs and sometimes the dealers forget to include the extra pair.

You can download the original brochures on the Monaco website. These are great as they show the available floorplans as well as options/standard equipment.

Last, be careful of pricing. Prices are all over the place. I've found some Dynasty's for $89k and other similar models for $149k. Check NADA bluebook (be careful of the bluebook options list as most "options" were standard equipment) and take your time. You will learn something from every one you look at.

Thanks, this is all helpful information. I contacted Cummins and was told the wrist pin problem on the 400 was production date Oct 17,2005 - Oct 18, 2006 (Eng #'s 46463798 - 46603939) so will look close at the Eng #.

bpotter. Be advised that Cummins did not fix that wrist pin problem all they did was detune the motor and you can really tell that they detuned it when you drive one. Here is the whole recall

May 18,2007
Associate Administrator for Enforcement
National Highway Traffic Safety Administration
400 Seventh Street, S.W.
Washington, D.C. 20590
Dear Sir or Madam:
The following information is submitted in accordance with the National Highway
Traffic Safety Administration's reporting regulations, 49 CFR Part 5 73.6.
Cummins Inc. (Cummins) has decided that there is a potential safety-related defect with
respect to connecting rods in ISL CM850 diesel engines manufactured by Cummins and
installed as original equipment in those motor vehicles identified below.
1. Product identification and customer channels.
This defect involves Cummins ISL CMS5O diesel engines produced for recreational
vehicle applications between October 17,2005 and April 18, 2006. There are 2 159
engines in the subject population that we intend to campaign.
All ISL CM850 engines in the subject population are covered by this recall. The ISL
CM850 recreational vehicle ESNs eligible for this campaign range from 46543077 to
46603939. A complete listing of the subject populations by vehicle manufacturer is
attached in Appendix A.
2. Identification of the item: Connecting Rod
Engine Make: Cummins
Model: ISL CM850
Part Number: 3971 393
Function: Transmit energy from the piston to the crankshaft
3. Estimated extent of defect population.
Cummins estimates that approximately 3 3% of the subject population of engines could
experience a connecting rod failure. Cummins will pursue a 100% recall on all engines
in the subject population.
Cummins notes that the Company has voluntarily decided to conduct this recall.
Cummins Inc.
500 Jackson Street
Columbl~sI,N 47201 LISA
Phone 18123775000
(4 pages)
4. Description of defect.
The connecting rod contains a machining defect in the wrist pin bushing of the rod that
could cause a seizure of the piston pin, which if allowed to progress, can lead to engine
failure with the possibility of the rod rupturing the block cavity, oil and debris on the
roadway and vehicle crash.
5. Chronology of events.
Over the later months of 2006, Cummins received reports of ISL CM850 engine failures
of recreational vehicles in the field. The failures were occurring on ISL CM850 engines
built after October 1 7, 2005.
In response to these reports, Cummins Service Engineering and Cummins Product
Engineering investigated the failures and coordinated problem solving activities. On
May 11, 2007, these activities led to a management decision to conduct a safety
campaign on ISL CM850 recreational vehicle engines built between October 17,2005
and April 18,2006.
To date, Cummins is not aware of any injuries, fatalities, or crashes that were the result
of this defect. It is estimated that approximately 3.8% of the subject population could
experience an engine failure.
6. Remedy program.
Cummins will recalibrate the engine control module. Additionally, Cummins will
enhance the Engine Protection System enabling it to provide early detection of the
failure mode and avoid more serious engine damage and resultant safety hazard. This
will involve installation of a new valve cover with a crankcase pressure sensor. Prior to
failure, the new crankcase pressure sensor will provide a signal to the dash with a red
light. A red lamp gives an indication to the driver to stop the engine as soon as it can
safely be done The campaign will be completed without charge to engine owners.
Cummins notes and emphasizes that all covered vehicles involved in the campaign were
sold with a 5- year or 100,000 mile warranty and are estimated to have extensive
warranty coverage remaining on these engines to cover future repairs as needed.
7. Part 577 notice letter.
The customer notice letter is in the process of being prepared and will be submitted in
draft to the agency as soon as possible.
8. Conduct of recall campaign.
Subject to concurrence of its OEM customers, Cummins will be conducting the
respective recalls with the customers of each OEM.
9. Customer/owner notifications.
Notifications are expected to begin in July 2007, once Cummins is in receipt of the
OEM recall authorizations and customer lists.
Please advise the undersigned of the recall campaign number assigned by the Office of
Defects Investigation to this recall. Cummins campaign code for this recall will be
Sincerely yours,
