I run tons literally tons and tons of pellets to TSC lol, usually starting iat the end of July until mid March, nonstop.
We load 22 pallets on my truck (44,000lbs), the heavy haul flatbeds haul 44 pallets at a time.
Did you get your pellets from Michigan? There's 2 pellet mills in Michigan, one in Holland - Michigan Wood Fuels and one down in White Pigeon - Fiber Byproducts (Pro Pellets and Magic Sparkle brand).
The mills make horse bedding too, it looks just like the fuel pellets, but you're not supposed to burn it (people do though and it's hella dangerous because it makes a lot of ash)
