    Looking at a 2012 Mack CHU613, It has a camelback suspension I’ve never heard of this type of suspension. Does this type ride really rough? Is it good off road I pull an end dump and do a lot of off road driving on rough construction sites. By the looks of it doesn’t seem like it would need much maintenance. I assume it’s impossible to dump the suspension like a normal truck. Any thoughts on this would be greatly appreciated.

    The Mack guys love it for durability. Ride? Meh! No you can not dump the suspension.
    Daycabinit and Tb0n3 Thank this.

    They're great for dump trucks, and by that line of thinking I expect dump trailers would do well too. Macks have a well earned reputation among local construction truckers and those camel backs are nigh indestructible. Best put some air in your seat though. At least when running empty.
    Daycabinit Thanks this.

    I dunno how a tractor would ride with the Camelback suspension, but I have an uncle that runs an old R model dump truck with it. He loves it, and it really doesn't ride bad at all even when empty.
    Daycabinit Thanks this.

    The Camelback is pretty decent for heavy vocational work. It's very durable. My Kenworth utilizes a Hendrickson walking beam (on 46,000lb springs), so is probably somewhat similar. I have found the newer Camelbacks to actually ride smoother than my old truck with walking beam, so Mack has obviously refined the spring pack in the last 20 years or so.

    It's a great choice for rough terrain, if you need the articulation, with little to no maintenance requirements.

    That said, you will never forget what you're driving, especially when empty!

    Still better than rubber block though. Just say no to rubber block, trust me...
    Marco231, Daycabinit, bzinger and 3 others Thank this.

    It's why I wear a back brace most of the time 40 years later. None tougher, you just can't sit down. I'm surprised that was still offered these days.
    Daycabinit, bzinger and magoo68 Thank this.

    Does it have rubber or bronze center bushings? Tough suspension, but not cheap to maintain.
