I suggest you list the Cummins owned shops.
They are for trucks and RVs. Navistar and cummins are the only on road engines for big vehicles. Cat is out of on road applications.
Thanks John for this comment. We will absolutely look into adding Cummins-owned stops to iExit in a future update. If there are any other suggestions for businesses/amenities we are missing for truckers and RVers, we would love to hear any and all suggestions.
