Would having a belly pan that starts at the existing bumper/spoiler and angles down to cover the axle work instead of adding an air dam? I've been reading all I can on this forum for about a year but don't recall seeing that discussed.
If you are suggesting using the bedliner from below the bumper angled downward, it sounds like a better design for an off-road skid plate than for improving aerodynamics. Big Dave on this site has had good success with a big air dam on a full size truck. I really do like the idea of repurposing a discarded bedliner as belly pan material. Could you try an airdam and a lowered belly pan below the differentials like BamZipPow's Toyota?
