    Hauling logs is more suited for air trac.

    Although it is rated at #38,000 lbs., from personal use I believe you would be satisfied with it. To me I it rides better at 85-88k than at 80k.

    Rides tougher than #### is just about right. I have air trac on my 389. HORRIBLE. my uncle and cousin have low air leaf rides 10x smoother. #### air trac

    Do you have any rough idea what it costs to buy a new Primaax suspension? I'm guessing astronomical? I'm interested in just a single axle...
