As with the post by oilpan4 above, the already low independently-suspended cars have it easy . . pickup trucks (and derived SUV's) are a bit harder to figure (cooling needs, suspension articulation, etc; the things that an "underpan" might prevent from allowing full work ability from the vehicle) for those of us contemplating this. My truck is not an off-road vehicle -- that might be the line not crossed for this -- and the problems of keeping that kind of limit from declining is fundamental.

Thanks from me for the "idea" of seeing this vehicle type from top and bottom as being complementary for best execution, I had not seen this clearly. May well make an underpan more realistic. I'll have to look at FF ground clearance (IFS) as I have not looked at it before (Post #9).

The truck I have is -- like others -- ultimately limited by cooling capacity (climate & terrain against HP demand) where gearing might be optimized (raised) for better FE when solo. But problematic when towing (for a gasser, just when loaded heavily solo). Grill shutters are one approach, yet egress of heat exchanger[s] cooling air is just as important to include when thinking on a pan as an aero aid.
