I have tried. Finding parts for these things is like a needle in a hay stack. I did find the best info at rv.net. Good help there but end results, 1 company makes the factory replacement and it is the company that makes them for the factory. $2100 plus shipping with a 4 week turn around time. Detroit Radiator quoted $1400 and 3 days. Got it clear to Detroit and was told $2000 and 3 weeks. That pissed me off. Sure is nice to have the features of the motorhome but damn, the truck never gave me problems.
