I made some minor changes to my Formula One truck...
The truck is both a transport truck and a mobile control center for the race. Maybe it's not very realistic... e.g. tools and radio are hold outside, but it's coherent with the old town style. The colour is not just a coincidence...
the thing that is unrealistic is that it s 4' wide, it really should be 6' for a right scale, otherwise it s pretty cool! you could do worst than to look at my racing semi, I m sure it will inspire you, it s farr fetched, but, it s fully functionnal, yours have that nostalgic 70-80 s charm, and you re not alone liking them.
