Sur5er, you must eat a pretty big pizza!!! I wish I could find a 29" wide pizza somewhere. And from a stone oven! Mmmmm....
There is a place I was that had something like a 22" pizza, and it was fantastic. We ordered a dozen of them for our boy scout troop on an outing, man the kids eyes lit up!!

I use a piece of cardboard in the winter. I don't cover the entire radiator, just about 80% of it. I don't worry about air getting through the trans cooler or intercooler because the cardboard is behind them and when I'm moving air is flowing through them. I put cardboard in when temps are below zero for a while. I take it out when it gets back in the 30's.

 

Guys , for you that are having problems with overheating, it sounds like you don't need a winter front if your truck isnt having a problem making it to operating temperatures. Plain and simple.
I only use the
" special winter front / tastebud goodness delivery container "
when its so cold out that I cant get the truck up to temp. ( 190* or so) . I usually wait till temps are staying below 30* which is generally jan-feb. here.
