[sleeeper]

I would really like to smooth the underside of my truck as a lot of air passes under (ground clearance is high and is needed off road so no lowering). I plan on extending the air-dam a little but again need the clearance. I have covered the gap between the body and frame rails with some thin polyethylene sheeting. I am curious if anyone has any advise on negotiating the drive shaft and rear axle on a truck ( has an independent front suspension). I know a couple of members have put belly pans on trucks but have never seen a picture of that part. I have some skid plates that came from the factory in the front and under the gas tank and am thinking of a pan from the back of the transfer case to the front air dam and a rear piece that starts tucked up behind the rear axle and angles up to the rear bumper covering the spare. maybe an aluminum panel over the exhaust.

I plan on an aerocap in the future, but right now it has a snugtop cab-high canopy. I jack the tire pressure up on the highway and obsess over the scan gauge. In this configuration I am consistently getting 21 mpg on the highway-way worse in tow, with the 4.6l v8 auto (scan gauge and hand calculations).
