Update: the winter cover does seem to help up in Calgary, and I'm HOPING that it will help reduce the DPF clogging rate - my daily commute is rather short, and with the winter cover on the truck is getting up to much better temps and faster...
For those interested, with cover on, my temp was about a steady 97 Celsius (coolant and oil) on highway at around freezing temps (0). On my short commutes (10 mins city driving) with below freezing temps, it is warming up to high 70's C or so with a couple minutes of idling before take off.
Sorry I don't have exact figure comparison of before without cover on: I was just looking at needle and it never really got that high on my daily commutes...
