If you only have two ALS units for 75 miles, there is a simple solution... MORE PARAMEDICS!!
Usually the EMTs who complain about Paramedics not respecting them are the ones who are either too lazy or scared to go to Paramedic school, or have tried several times and failed. I'm sorry, 120 hours does NOT qualify you to perform invasive procedures. Sure, you can start that IV, but what do you do if you suspect you've caused an air embolism? For a CHFer, would you attach saline or just a lock? What happens if you give too much Narcan to an unconscious overdose patient? Your patient is having a Right Ventricular Infarction... would you give them nitro? Can you give Bicarb and Calcium through the same IV? How does Bicarb work? What does it do? How does Calcium work?
I'm sorry, but 120 hours with a few 16 hour "extra cert" courses should not qualify you to administer ANY medication. You have less education than a hairdresser and you want to inject substances into somebody that will alter their body chemistry? Substances that alter how their body is working at the cellular level? Substances that could kill them?
When I finished my EMT class, I had training. Now that I am finishing my Paramedic schooling, I have an education, and I am going to be continuing on to higher education. Yes, there is a difference between training and education... for example, would you want your daughter to get sex education or sex training? Think about it.
