Hi Connor,
you’re right, under this conditions charring some wood is challenging.
There is a thread about avoiding smoke during charring because of the same problem.
Maybe this can give you some good ideas?
With a wood-gasifier it is also sometimes impossible to avoid some smoke during lighting, refueling or working on it. Of course it can be limited by proper handling.
Just keep this in mind.
Not to discourage you, but as many others already said it, be realistic on your situation (wood supply, vehicle limits, neighbours and so on) to avoid later frustration.
