I love the way those look and definitely seem mor heavy duty than my heat shields.
I like the heat shields because they are rigid and flat so I can sneak them into all the little voids in the truck when in storage mode
The more sealed the vehicle the more condensation forms. I usually drop my heat shield a few inches and crack the windows. When I keep them all fully sealed up the interior steams up pretty good.
Of course outside air temp is a factor but in all cold camping I keep sunroof open or windows...
Another vote for heat shield. Mine are going on 5 years and holding strong. I keep my third row panels installed year round. I lucked out and got black on one side and silver on another. Now they only offer gold and white , I think??
Their warranty is great if you have any issues and CS responds...
