Not sure where you are or what you have but I use Cummins Crosspoint in Normal, IL. They are a fulls service Coach Care facility so they can work with all chassis and coach issues. I would suppose the only potential "problem" would be if you needed serious work on a CAT engine or perhaps a non-Allison tranny.
I have used them for a year with the first 8 months being a Winnebago on a Workhorse chassis and now my DSDP. They have provided me good service and been timely when factors outside of their control such as when the Koni Distributor took several days to get shocks to them. They have been extremely patient with my learning curve and my picky ways too.

If you contact them tell Teresa that Don with the "new" Dutch Star says hello.
