There are a bunch of cab heat threads and winter driving threads. Thought I would add this to the mix.
I stole the idea of using a 4" flush deck hatch cover to tap into the radiator heat flowing through the center trans channel. My improvement was to add a 4" ABS "T" from a dust collector to push the warm air into the footwell.
Well, at 10* it kind of worked too well. Damn near melted my boots!
We run a half windshield and the only complaint was a draft from the back of the cab so considering a lower half rear windscreen.
Figured that if it might come in handy for routing a hose to back flush the radiator when she fills it full of mud too.
