The new diesel emission standards have been a huge pain for the emergency vehicle world. The vehicles idle too long and don't get driven long and far enough to passively regen and clean the DPF.
There, I added a little detail (in red) to your comment. Besides not getting driven far enough to start and complete a regen cycle, they are also idled (or fast idled for PTO) often so that the filter quickly fills up. Yes indeed, lots of idling and not enough over the road driving can be a real problem.
