I think the Cummins-Onan service center in Spartanburg SC runs a mobile maintenance & repair truck around their area to do work on stationary generators for hospitals, schools, and such. I've seen them as much as 100 miles from home base years back, but I don't know if that's common. I know the shop works on RV generators (rebuilt my Microlite 2800 under warranty), but I don't know if the truck does, and I don't know where Dillon is. There's also a Cummins-Onan service center in Charlotte NC.
