I wish you good luck with them.
The company I used to work for bought out another ambulance company and Demers were all that the new company owned. They were big POS in my opinion. They were not very user friendly. One very annoying thing that Demers is known for is the not bypassing the OEM horn when using the siren. You would get OEM horn every time you changed siren tone with the horn.
I stand corrected with the horn issue. I don't know why any ambulance manufacturer would decide to keep the OEM horn active, but it's the most obnoxious thing in the universe while responding, because I prefer to exclusively use the horn ring for the siren.
I rode my first shift in this truck yesterday and, while I mostly love it (it's very user friendly in the back, I kept discovering some really good features), there are some glaring design flaws that need to be addressed and fixed.
The main problem I noticed from this truck is that there is no way to lock/unlock the rear doors from outside. And inside, you can pull up the lock to open it, but there is no lock/unlock button in the back. In order to open the rear doors, someone has to go to the front and turn on the truck, because the unlock buttons also do not work at all once the truck is shut off.
Also, both front turn signals activate as hazards in both (left signal/right signal) turn signal positions. Not quite sure how that happened, but that put the truck out of service until our barely-competent mechanics can figure out how to fix it.
