My take is that if those light bars are what put him over the edge, removing them might help. But given that they aren't that big, he's probably still going to be near the edge when towing in hot weather, which isn't something I'd want to do. But I'd be willing to bet that everyone who's installed this IC is in the same boat, just that they haven't yet been in a situation that pushed them over. If you're after big power and don't mind throwing money at the problem to get it, then that's cool. But for those who just want to install a winch, I can't imagine a lousier solution. I mean, if a new radiator is the new answer, then you're talking three grand just to move stuff out of the way, and then the cost of the winch and install. You could put $5k into it easy which is stupid for a winch.
The issue highlights the fact that someone needs to make a dedicated solution just for getting a winch in place. Instead of putting in a giant power oriented IC, what we need is a simple kit to relocate the existing IC and fans. It's what, a third the size of this monster? Then if someone would make an anti-raptor grille kit that eliminates the giant FORD, then you'd probably end up with similar airflow to the radiator as stock. If someone could put together a kit like that for $500-$750, they make a mint.
