I have used Cummins Coach Care, in KC, MO, for 5yrs. and 2 different motorhomes both on Spartan. My experience has been very good and will continue to use them. Mostly for routine servicing, but have friend with a King Aire that uses a Coach Care in IL and he has been very statisfied having all sorts of items fixed. In my experience, once you make an initial intro and service, when you need help on the road a call to your main Coach Care will get you lots of help.
