Did the roller function? If so, that's a slick piece of offroading genuis right there! Can't believe we don't see this more on modern trail rigs and such... Would be great on the rear bumper of trucks too.

OK, so the picture linked of the Baja truck is what I was talking about in the first post. How would a boat hull-esque front, impact FE and other mods that are normally done for FE? It would drastically change they aerodynamics of the vehicle by forcing more air under the car, the opposite of what we normally do right? Although it would be a much smoother and controlled flow, would it lead to decreases in FE, would it generate lift or cause dangerous conditions at high speeds when combined with full underbody tray?
In regards to design, would it need to be a tapered design like a true boat hull?
Or could it be flat like the duck tour amphibious trucks?
Clarification: would you want it tapered to try and cut through the air forcing air around the truck like the wake of a boat, or flat simply to try and provide a slippery angle for the air to hit and slide down under the truck? This is about as far from traditional aero mods as it gets, from what I can tell...

I just wonder how easily it would rip or crease under stress. Of course that would be remedied by having a cordless drill, patch sections, a rivet gun, and silicone caulk in the back of the truck

I had actually thought about heatshield on the underside of the truck and on the belly pan facing the exhaust... Although that wouldn't lower heat in the space, simply protect things from the heat. Exhaust wrap might be the answer! Although I'm not sure how that will impact performance or longevity of the muffler with out it's natural ability to be cooled in the wind stream under the vehicle
