Talking aero truck project begins

I have my cap and skirts on (no, it's not graduation day!) my first tank on the 1992 Toyota truck netted me 30.8 MPG. I'm shooting for 36. Anything over that is bonus. More to come.....Click image for larger version

just shock and strut suspension, but future plans call for an underbody panel(s), and lowering. I have to get some welding done on the frame, so I figure when it's on the lift would be the best time to lower. My big mirrors are gone and replaced with small aeros.I have also added wheel skirts.. i'll get some new picts on a less crappy day

Thanks! I used some "FRP" panels (like what you see behind urinals in bars) and CPVC pipe for a frame. so far, it has survived some 80 degree days in the sun, and comes in at probably less than 30 pounds. I haven't weighed it yet because it was a pain to crawl up under and mount. lol!

I hate to be a drag (pun intended!), but the transition angle from the cab roof to the aero cap looks pretty steep. A quick Photoshop estimate looks like about 15 degrees. Have you tuft tested to know if it's working?

I used an angle finder gauge after I built the frame (backwards planning at it's best) and I had about 15 degrees at the top third, 12 degrees at the center, and 10 degrees at the back... In retrospect, I would have taken more time on the angle, but I was P.O.ed at big oil and just wanted to get something started, then I got the bug!

It'd be just about perfect if you'd done 10, 12, 15 front to back
