Specialized app's and DPF's

Lately i have been seriously contemplating getting a new boom truck to replace my old 1989 F-800 with a national 556A unit on it.

But the thing that has me NOW worried is what happens when the truck decides it wants to go into a REGEN when I'm in the middle of a pick? a sudden surge in engine RPM while swinging a load could lead to a shock load and taking the whole truck over with it.

I'm I supposed to make a 10 man crew wait while the truck goes through a regen cycle? its not like a highway tractor that will see heavy loads driving down the highway. My current boom truck will idle for 8 hours a day for a week or longer on bigger jobs.

This application isn't like a wrecker where you set the throttle up and leave it. You use throttle to control the speed of your movements along with modulating the controls.

Any one have any thoughts on this or am i way off base here? Is there any way to get a Exemption from having a DPF on a new truck chassis?

I remember seeing some literature somewhere that if the engine is put into PTO mode, the regeneration is disabled to prevent the engine from idling up. I saw this in a presentation for the DPF's in heavy duty trucks, so it should apply to a newer boom truck. If I come across it again or remember where I found it, I'll post the link.
