Thank you VXorado.
I never wanted this to become a p*ssing contest, just some friendly advice.
I have no problems at all with the fans being behind the radiator, and having a shroud. In fact, a shroud is a must.
It is the amount of radiator that you are blanking off that will have no effect on how the fans work, but will seriously restrict the amount of air flow through your radiator at highway speeds.
Whatever you end up doing, I hope it works for you.
If you end up in Moab next year, I hope we can shake hands and have a beer as we look at your rig.
