    onan 5500 oil filter replacement

    Hello,
    Time for the annual oil and filter replacement. I cannot find a real Onan 122-0836 oil filter locally or online. The ones on Amazon have some shady reviews claiming missing o-rings and/or being knock-offs. Googling other forums, it seems like this filter is in short supply. I have seen a cross reference list, but even there, I have read complaints of other filters not fitting right or being too short.
    Anyone found a good replacement for the Onan 122-0836?
    thanks all
    Rob

    Carquest & Napa are both made by Wix.
