What do you think?
We're looking at a 40' 2006 American Tradition with a cummins 400 ISL, independant front suspension, tile floor and all of the correct goodies. We've never owned a DP, so I need to ask if the 400 ISL...

Sorry I did see this post before. My only concern for you is the ISL wrist pin issue. Here is the notice. I hope this does not apply to you.
This defect involves Cummins ISL CMS5O diesel engines produced for recreational
vehicle applications between October 17,2005 and April 18, 2006. There are 2159
engines in the subject population
The ISL CM850 recreational vehicle ESNs eligible for this campaign range from 46543077 to46603939.
A complete listing of the subject populations by vehicle manufacturer is
attached in Appendix A.
Estimated extent of defect population.
Cummins estimates that approximately 3.3% of the subject population of engines could experience a connecting rod failure.
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.
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 17, 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.
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.
Customer/owner notifications.
Notifications are expected to begin in July 2007, once Cummins is in receipt of the OEM recall authorizations and customer lists.
