On my trip out to and back from Los Angeles...my side skirts had a tendency to come off and drag. Since this is all experimental...it wasn't a total loss. It did scrape on the speed bumps in the parking lots. The foam part on the passenger side did snap off after the coroplast got peeled back. If I left the front mud flaps on...it probably would've protected it a little better.
So I would still consider it a success...needs more work fer the moment.
I only had my standard load of tools and gear. About 300 lbs or so of stuff in the back.
Currently have all my side skirts and belly pan off fer the moment while I git ready to fab up in aluminum framing and sheeting. To separate the front belly pan from the main belly pan, I'm putting in a crossmember so I can take one off without messing the other.
My design will also allow me to take either belly pan off with about 4 bolts.
During the course of my testing, I tried different speeds to see what effect it would have. Even got pulled by a sheriff fer doing 51mph in a 40mph (min)-70mph (limit) zone at night. What a crock that was...
