Hi, I had a similar problem with my traction engine, I wanted the smoke to follow the engine around a long track and go around the curves leaving trail of smoke. Smoke had lots of problems I could not find away around.
In the end I opted for a particle system instead of real smoke. I made a cube with volumetrics and a similar node setup as if it was a cloud (sphere gradient for density with noise texture etc) to use for the particles. As it is a particle system you have a lot of control over the effect and you are not limited to a domain (and its resolution etc). The actual particles I used are quite large in size, I did adjust their size and rotation over their lifetime.
Here is a link to the tread with an animation of the smoke.
Maybe this approach could be useful.
