MK 2...

Copied a Kenworth T680 sleeper cab onto roof...large compound radius, and helped also remove the sun visor easily from the picture
Added some side deflectors between cab and sleeper .
Lowered fender height by around 3"
Defined (Would need smoothing) the drivers step / side skirt width change section slightly...this would need flowing and rounding out at rear edge, and a transition from the fender directly onto it..
More suggestions the merrier..
I am in liaisons with a thermal airflow expert for the engine cooling, a radiator specialist, have a staff member onhand who can make ANYTHING in fibreglass / etc (has made entire WW2 plane replicas).
I will be also looking for government funding for green purposes on the R&D side of this..the first 1-2 prototype conversions may end up costing VERY little..
