Forgive me if this is already somewhere else on the site. I've spent over an hour searching and have found one mention of PP issues. My bumper will require a Powerplant to sit on top. Has there been any overheating problems, or anything else with this monster sitting up there on the front?

 

I haven't had any problems yet and I've been on a 6 hour freeway drive in 100 degree heat and also out on the trail. It does tend to run a bit warmer though.
I do hate that Warn, maker of both the winch and the bumper I have, couldn't have come up with a better fit.

 

You could always buy a bumper that sits the winch lower between the frame rails, so it blocks less of your radiator. Here is a shot of my Powerplant and Shrockworks bumper............................

 

thats part of the reason i got my shrockworks.
