Noticed the new 2019 PC "Upgraded" Standards includes "Double Insulation", heat, sound & noise abatement - Ford Cab. When I ordered my 2016 E350 - 2351 that was a topic floating around that many requested PC add but I was told may void the "Warranty". Looks like Ford/PC have resolved this. I believe one owner back in 2013 ordered replacement insulation and did the task themselves (I am sure not necessarily an easy project).
I was wondering if anyone recently has taken on this project and do you have the product info.
Thanks,
John
