I have researched this option a lot as I will likely be deleting once my warranty is up. That said it's not too bad tracking your exhaust filter status % on the screen, and then making sure that if one starts, you let it complete. In the end, you just want to make sure you don't get suck in the regen loop where you're not cleaning it out fully all the time (i'm sure you've seen the "stuck in regen" thread. Ford has even decided to hide this from the display as they don't consider it critical for drivers to know. Lots of us track this however just so that we're ensuring full regens are completed fairly regularly.
As for the delete process, the DPF is a physical filter, so you can't just turn it off with forscan, if you did, it would simply plug up, and your truck would slowly die. Good news is that it's fairly easy and cheap to delete. A single tune from a tuner with the gadget runs around 800 CAD, and an exhaust system runs from around 250 CAD to 500 CAD. That said, make sure you check your states emission laws and requirements and consider that in your decision, as well as your warranty. I have 57,000 km on my truck, and have had zero issues with the emissions system, no matter how hard i try and find a problem. So I think ford has figured this out pretty well now.
