    I find that hard to believe. See here, when I operate a CAT 936 front end loader wheeled to feed a ready mix as I have, sand in the bucket something like 7 yards is not as heavy as a bucket load of stone.

    Ive been weighted with Maryland State Police standing on my ### eyeing the scoreboard inside the coop, and it's 9 ton under sand or 22 under stone.

    Think about volume. Take a one pound bag of sand and it's smaller in size compared to one pound bag of stone.
    There is a lot of air space with stone.

    Now with your two bags of sand and stone, fill a five gallon bucket. The stone will fill the bucket in fewer bags than the sand. Say it takes 10 bags of stone. But the sand bucket takes 15 bags.
    So the stone bucket weighs 10 pounds and the sand bucket weighs 15 pounds. Both filled to the same volume, the more compact less air filled sand will prevail.

    Per Google, 1 cubic yd of sand weighs 2840 lbs and 1 cy of crushed stone weighs in at between 2600 and 2700

    Also from my experience, the weight of sand can be greatly effected by moisture content more so then stone

    I have made a hopper bottom full of money hauling sand. It takes just a minor amount to hit 26 ton.

    A 936 with a 7 yard bucket? Ok. Anyway a bucket of stone will heap, sand will not. As far as your scale comment, there's NO WAY stone weighs twice as much a gravel so I'm not following the 9 ton 22 ton statement.

    I hated driving a 32 foot end dump. Anything more then a slight curve and I was slowing down.

    Plus, I always got the tightest deliveries because I could get in everywhere (allegedly).

    When the weight is stuck in the nose of the trailer it's doesn't matter if it's 32 or 39 you can tell your center of gravity is way up there.

    If it were me I'd get a 39 ft. You can do local and if that slows down then you can do OTR and vice versa.

    Small piece of plastic on the floor of the nose helps a lot, also helps with not having to shovel, I was terrified of my 40' when I first got it but now that I've had some good 32-39 ton loads up in the air you realize they aren't as bad as people make them seem. Just can't hesitate and either have to put it all the way up or slowly bring it down to reset

    You need to check your local laws to see what the weight ratings are, pretty much the whole north east minus D-bag CT allows us to get an overweight permit for atleast 99,000 gross.

    Nobody even likes CT, they should just leave. CT should go hang out with CA.

    You Goulet and Cedar Hill guys can have that landfill work. My first day on a job was hauling dirty dirt and dear god was it nerve wracking. Not for the fear of dirt sticking but the sponginess of the ground. First load I went to pull ahead and pass sunk a ft, pull ahead bit more driver side sunk... Nope, F-that. Did 2 more loads and told dispatch that's not for me or safe for trailers.
    Didnt help that the dozer guy was a jerk. He said he didn't have time to cut a hard spot for trailers and he'd been there 25yrs and seen plenty go over but it was just part of environment.. I got myself off that after the first day but another company had a brand new quad axle up there a couple wks later and flopped it.
