Is Mastodon Moving LLC reliable? Our read of the record
On the evidence, Mastodon Moving LLC looks like a reliable operator: operating since 2011 with zero federal complaints in the last four years, 8 registered trucks, liability insurance on file without recent cancellations. A record like this is exactly what an honest mover's file tends to look like.
No public record can guarantee your specific move, so keep the basics: written binding estimate, USDOT 2174430 on the paperwork, and reasonable deposit. But nothing in the federal file says walk away.
This assessment is generated from the public federal records shown on this page: registration, fleet, complaints, inspections, insurance and authority filings. It is a summary of records, not a review or an accusation.

About Mastodon Moving LLC
Mastodon Moving LLC, doing business as Mastodon Moving, is a federally licensed household goods carrier based in Westborough, Massachusetts, registered with FMCSA since July 2011. Federal filings show 8 power units (trucks/tractors) and 12 drivers.
Over the last four years, the federal complaint database shows no complaints against this company. For a mover doing real volume, a clean federal record is a genuinely good sign; for a very small operation it may simply reflect a small number of moves. Combine it with the fleet data above and recent references.
How to read this report
The grade and risk score at the top are calculated by MoverAudit from objective federal flags: whether the company is a broker or a carrier, how many trucks it operates, the volume and severity of complaints, hostage-goods reports, and past authority revocations. They are not official government ratings, and they are not reviews: every input is a public federal record shown on this page.
The complaint categories come from the FMCSA household goods complaint system. A single bad move can generate complaints in several categories at once, so the category sum can exceed the total. Pay the most attention to "Hostage Goods" and "Deceptive Business Practices": those describe intent, not accidents. "Loss and Damage" at low volume is normal friction for a carrier doing thousands of moves; the same number at a tiny company is not.
The fleet numbers matter more than they look. A company advertising nationwide service with zero or one registered truck is not doing that work itself: your move will be handled by someone you have not vetted. Compare the fleet size to the promises in your quote.
If you are considering this company, use this report as a starting point, not a verdict. Get the estimate in writing and check whether it is binding, confirm the USDOT number on their paperwork matches 2174430, and if a different company shows up on moving day, stop and check that company here before a single box goes on the truck.
