2012 Newmar Essex input

Does anyone have any input on what to look out for on a 2012 Essex, 52k on it.
Any input or items to question and look at would be appreciated.
Thank you in advance!

Cummins engines of that era I believe had some emission equipment issues.

Go to “ Power Train Garage” “Cummins Engines” on this site and search the ISX engine. Check to see if the engine in that coach could be one that may incur the #6 valve failure problem. Read many post about the cost of this repair. If you go forward with the purchase, make sure you’ve factored in that cost with your offer.

Thank you for the reply Tom, it has the ISM 500 in it..........
I am very familiar with the ISX valve problems...........that why I am dropping back looking at the ISM 500 engine.
Any input on the emission problem's with the 2012 ISM 500?
Thank you again for your post!

Check that section of this site and you might find info on any emissions problems.

Now after researching that year I believe the dealer listed it as a ISM engine but I think it is a ISX..........Cummins stopped the ISM in '09 I think??
Same possible issues With the valve's in the ISX 500? I remember reading on here about this problem with a 500 ISX along with the 600/650 ISX engine's?
Getting gun shy here now! Waiting on the dealer to get me the serial number..........

Also see if it has E-Plex and not the newer Silverleaf coach controls. If it has E-Plex no parts or support.... walk away

There is support for Eplex but it is on the expensive side.

I have a 2007 Essex with Eplex and had to fix the automatic generator start. Eplex wanted in the neighborhood of $1,000 for parts. I fixed it for under $300 with used parts.

Yes, I went back and read Lady Puffin's post's............but Since she first posted here, and me searching the net, Hers is the only 500 that I can find...........
Not saying that is great, one is to many! But it does not seem to be to common in the 500 that I can find, on all rv forums and trucker's websites. Thinking a lot of that bad stuff will be gone shortly after winter when I get it back to my shop..Like Ron did...........and maybe save it.
Thank you for posting.........Have a wonderful Holiday coming up!
