This ship was cobbled together.
As to the red mist, we know First Order stormtrooper armour does not filter toxins, so maybe a chemical weapon. The mist could be incendiary in nature, launching a bomb into the mist could ignite it.
Highly doubt the ship is going be mk2 anything, although they could have been cobbled together from other vehicles. The design is definitely based on the B-wing, but reducing the proud heavy fighter to a glorified sand skiff.... nah, no way they would do that. Unless there crashed/wrecked mk2's, and they've been repurposed for atmospheric fights, which is why they are barely flying so they have the center strut to hold them up.
Also the good guys probably aren't gassing their enemies. Cliche as it may be, maybe the smoke is hiding tow cables?
