That was one reason I switched to a DP. It is ea$y to get into most diesel OTR houses for chassis work. And I DO like having my own back up vehicle.
We had a lot of troubles one summer with our 98 F-53 460 on a two month vacation. It was a night mare getting anybody to work on it and it was as expensive as the DP.
As the DP gets older and things are starting to act up, I am starting to get worried. Reading another thread on the CAT C7 that needed new injectors had to cost thousands.
I am seriously toying with going back to an Airstream or Lite TT that can be towed with a 1/2 or 3/4 ton gas pickup.
They just don't break and you can get it repaired(or even replaced) anywhere.
