I would have no problem producing an LDD file for others to use. Not at all.
"Illegal" building technics don't bother me as long as it turns out looking the way I want it to look. I don't have any real Lego's at all and can't justify spending the money on them when I already have another hobby that takes money, which is vintage/older computers. So I build things on LDD and don't have to spend money at all and have an endless supply of bricks of any type I want.
That truck, along with the gangster-style one, and the white vintage car are the best-looking Lego vehicles in that small scale that I have ever seen.
Extremely detailed pictures would not be necessary, just a description of how the chassis are assembled. I have already figured out how you built the cab and bed on that truck and already have them laid out in LDD. It is the underneath part I can't figure out.
