advice on a 2010 Tiffin Zephyr

I have found a 2010 Tiffin Zephyr that I am seriously considering buying. It has 33,000 miles on it. I understand that this 10.8 liter cummins engine used a def system. If I remember correctly this was about when the def was starting to be used and I assume this is one of the very early systems on this coach. I am just wondering if anyone has experience with this engine and if there are any common problems i need to look out for. I know the common wet bay floor, slide floor and roof radius I need to look at. Any suggestions, concerns or warnings on this vintage Tiffin?

Thanks

    Or, many of the tiffinrvnetwork people also are on the Tiffin facebook page and you will get a much faster (but not necessarily better) answer to your question.

    You might consider joining and posting your questions on the Tiffin Owners forum.

    There are a lot fewer Zephyrs around than other Tiffin models, but there might be someone there that can help.

    Update: A little web searching indicated that it may have a pre 2010 ISM engine or possibly an ISX engine. I suggest you try to get the engine serial number and verify with Cummins.
