Considering Diesel International/ or Freightliner Ambulance Conversion

The ‘Choosing the right Vehicle’ category is for anything related to the discussions, questions, comparisons, & information about living in different types of vehicles.

I met someone that had a large ambulance which is not a type I have seen before that has a diesel engine with a semi truck front on it, It looked like it is likely more durable, reliable, and even cheaper than a box truck and I am trying to now research it because it seems like the best option.

Does anyone know about the best way to aquire, maintain, register, drive, convert, upgrade, etc. or know any specific information about these diesel ambulances (here is a picture or 2)
