    Do the heavy-duty diesel engine emissions have a 8-year/80,000 mile warranty period like the "cars" do? Per the federal requirement - or does that only apply to cars?

    Most motorcoaches (Monaco, Newmar, Tiffin Thor/Rev, etc.) which usually cost upwards of $400K (some are in the millions) only have a one or two year warranty. It's crazy someone would spend that much money and not get a longer warranty from the manufacturer. On RVs, the mileage is typically low so its not uncommon for a 7 or 8 year coach to have under 80,000 miles.

    Is the DEF, DPF, etc. covered for 8 years/80K ? This stuff is expensive to fix, and many Coach owners are complaining of failures in coaches that are under 3 years old (or less).

    The basic engine warranty (from Cummins) is only 2 years.

    I think due to the yet perfected technology on diesel emissions systems and the money that it brings in to dealers on parts & service it's never going to be a long range warranty item on a commercial vehicle. While they are better now than the earlier emission years they still require routine maintenance, which I'm betting the manufacturers don't expect many to do.

    I am not sure about other OEMs. I can tell you that every KW and Pete truck comes with 5yr 100k federal emissions warranty. This covers most of the components directly related to emissions reduction.

    This is not a purchased warranty, but standard warranty that is included with standard truck purchase.

    Bad thing is 100k goes by pretty quick.
