Also, this is probably “duh” for those of you who have more experience in this game, but I’ll post it as a learning experience for newer players like me:
The high damage potential for that MT I posted above is due to, I think, the scatter blaster installed in it. I tend to roll with just the boltcaster (plus a lot of mods), so when I removed the scatter blaster, the damge potential was much, much lower than advertised. With mods etc, the damage potential is roughly equal or slightly lower than the B class rifle multitool I have been using for most of the game, but the scanner radius is greater. I’m not sure if the mining etc is better or not.
