I'm a medic now but worked for about 6 years as EMT. I'm writing this assuming that the call types are the same no matter if a truck is ALS or BLS. Now, if you're saying that the only BLS truck would just do renal roundup and the ALS would do the majority of 9-1-1 calls, that would make a difference, obviously.
As an EMT, I would much rather work on a BLS ambo than an ALS. Even though there are many, many good medics who on less-than critical calls let their EMTs run the show....in the end the EMT is still "under" the medic. Also, on anything "good" obviously the EMT would end up driving on an ALS rig. Personally, being able to be completely "in charge" of the call on a BLS truck is more appealing than working on an ALS truck.
Now as a medic, I would rather have an ALS partner, for a few reasons. First, for the obvious help with skills and procedures on runs. Also, I like having the ability to switch off with my partner on calls....where as if there was a 1 Medic and 1 EMT ambulance, me (the medic) would get stuck with all the ALS calls and associated paperwork. Also, as a newer medic, I know I would be apprehensive and nervous about having an EMT (who possibly has years more experience than myself) work under me. Not sure why....but I know it'd make me nervous.
